From 0162567dc0973b37dcb0ba2fa3d63c8fedf7c38c Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Tue, 4 Aug 2026 15:27:23 -0500 Subject: [PATCH 01/16] docs(418): add feature folder and wire SVGControl.Test into solution - Add the active feature folder for the SvgRenderer null-document NRE: issue with AC-1..AC-11, atomic plan v0.3, root-cause research, WinForms designer verification runbook, and Phase 0 baseline evidence - Register SVGControl.Test in TaskMaster.sln with Debug/Release configurations for Any CPU, x64, and x86 - Correct the ExCSS binding redirect in SVGControl.Test/app.config from the non-existent 4.2.4.0 to 4.3.1.0 - Restore the Svg 3.4.7 package pin and add the compile-time Svg reference so SVGControl.Test builds - Record agent-memory entries for legacy csproj compile references, missing VSTO runtime effects on baseline gates, and new solution-member pin divergence - No production C# is modified;

This contradicts the atomic-plan-contract skill, the atomic-planner agent doc line 44, and 100% of existing repo plans, all of which use the em-dash. I kept the em-dash (contract + repo convention) rather than over-fit to the lone hyphen regex; treat the hook regex as a probable hook bug.

Only the first can carry an `InnerException`. This is the + asymmetry the plan's `GetSvgDocumentOrThrow` design records. +- Section 2.2 rules out removing the `<style>` element from the default SVG: the ExCSS bind + occurs when `SvgDocument.Create<T>` is JIT-compiled, not when the `styles.Any()` branch is + taken. The plan lists that approach as explicitly out of scope. +- Section 4.3 explains why the existing `AssemblyResolve` fallback returns `null` in the + designer host: `Assembly.Load` binds against the host AppDomain's `ApplicationBase`, which + is the Visual Studio directory, not the directory containing `SVGControl.dll`.

Task `[P0-T10]` captures + that state as observed rather than as asserted. +- Section 8.5 forbids a test that asserts the `AssemblyResolve` handler is absent, because the + handler is process-wide and permanently installed. It also requires disposing any `Bitmap` + produced by a success-path assertion. +- Section 9.2 (H-1/H-2) establishes that the designer-load check is not automatable and must + be performed by a human, which is the basis for `[P2-T10]` and for leaving AC-11 unchecked. +- Sections 9.3 (U-1, U-2) record two items that remain unverified by design. + +From the runbook: + +- The cue is explicit: run it after the toolchain is green (AC-6) and before the feature is + reported done.

The byte-array constructors at lines 126-142 dereference the result without a guard. This is a direct violation of the repository's fail-fast and no-silent-swallow rules in `.claude/rules/general-code-change.md` and `.claude/rules/csharp.md`. + +2. **Underlying parse/binding failure (root cause not yet confirmed).** An existing in-file comment at `SVGControl/SvgRenderer.cs:24-31` documents a prior occurrence: `Svg 3.4.7` was compiled against `ExCSS 4.2.3.0` while the repo deploys `ExCSS 4.3.1.0`, so `SvgDocument.Open` throws `FileNotFoundException` in hosts that ignore the project `app.config` binding redirects. A static-constructor `AssemblyResolve` fallback was added in commit `0b4c5c43` to compensate. Since that fallback is present on `main` and the failure is still reported, the actual current cause is undetermined. Candidate lines of inquiry: + - The WinForms designer host (`devenv.exe` / `DesignToolsServer.exe`) does not apply `UtilitiesCS/app.config` or `SVGControl/app.config` binding redirects, and the `AssemblyResolve` fallback may not be reached or may not satisfy the request in that host. + - `SVGControl/app.config:18-20` redirects `Fizzler` to `1.3.0.0`, but the deployed package is `Fizzler 1.3.1`. If the deployed assembly version is not `1.3.0.0`, this redirect targets a version that is not present. The same redirect appears in at least ten project `app.config` files. + - The hardcoded default SVG is emitted with `Encoding.ASCII.GetBytes`, which is only safe while the literal stays ASCII-only. + +The determination of which of these actually fires — and in which host — is the research question this bug opens. + +## Acceptance Criteria + +Acceptance criteria are grouped by the two defects identified under `## Suspected Cause / Notes`. AC-1 through AC-6 address the confirmed error-handling defect and are unconditional. AC-7 and AC-8 address the underlying parse/binding failure and are conditioned on the research outcome. + +- [ ] **AC-1 — Failing regression test exists first.** A deterministic MSTest regression test in `SVGControl.Test` reproduces the defect before the fix is applied: constructing `SvgRenderer` from a byte array that `SvgDocument.Open` cannot parse currently produces a `NullReferenceException`. The test is recorded as failing (pre-fix) and passing (post-fix) in the feature evidence. +- [ ] **AC-2 — No silent exception swallow.** `SVGControl/SvgRenderer.cs` no longer contains a `catch (Exception)` block that discards the caught exception without logging or propagating it. Any retained catch logs the exception through the existing `log4net` logger already declared in the file and either rethrows or returns a result the caller is required to inspect. +- [ ] **AC-3 — Parse failure degrades visibly instead of throwing a `NullReferenceException`.** Decided 2026-08-04: the byte-array `SvgRenderer` constructors must **not** throw. When the document cannot be produced, the constructor logs the cause at error level through the existing `log4net` logger, leaves `_doc` null, and initializes `_original` to a safe value without dereferencing `_doc`. A `NullReferenceException` is never the observed failure mode. Rationale: `PictureBoxSVG` is instantiated by designer-generated code in eleven forms, including `QuickFiler/Viewers/ItemViewer`, which runs inside the Outlook add-in. Throwing from the constructor would convert a blank-icon degradation into a control-construction failure for end users. + + The diagnostic must be observable in the WinForms designer host, not only through `log4net`. `SVGControl` declares a `log4net` logger but there is no evidence an appender is configured inside `devenv.exe`, so a `log4net`-only diagnostic may surface nowhere the operator can see it. The implementation must therefore also emit the failure through a channel the designer surfaces — `System.Diagnostics.Trace`/`Debug` output, which appears in the Visual Studio Output window — in addition to the `log4net` call. Both channels must carry the exception type and message. +- [ ] **AC-4 — A fail-fast API exists for callers that want it, and every null-tolerant call site keeps its contract.** A public API on `SvgRenderer` reports parse failure explicitly rather than by returning `null` — either a `Try`-style member that surfaces the captured exception, or a throwing overload that raises an explicit exception whose `InnerException` is the original exception from `SvgDocument.Open`. The existing null-tolerant consumers (`SvgRenderer.Document` setter, `SvgRenderer.Render()`, `SvgImageSelector.SaveRendering`, `SvgImageSelector.ResourceName`, `SvgImageSelector.UseDefaultImage`, `SvgImageSelector.SetDefaultImage`) keep their current tolerant behavior, and no call site is left dereferencing a value that can still be `null`. +- [ ] **AC-5 — Coverage on changed code.** New MSTest coverage using Moq and FluentAssertions covers the success path, the parse-failure path, and the argument-boundary paths of the changed methods. Coverage does not regress on changed lines, and newly added members reach the `>= 90%` threshold required by the C# unit test policy. Note that `SvgDocument.Open` has two distinct null-producing paths: malformed input throws (`XmlException`), while element-free input such as `Array.Empty<byte>()` returns `null` without throwing. Both paths require coverage, and only the first can carry an `InnerException`. +- [ ] **AC-6 — Toolchain passes in a single clean pass, measured against the recorded baseline.** CSharpier, the .NET analyzer build, the nullable/`TreatWarningsAsErrors` build, and `vstest.console.exe` all run in one consecutive pass in the order given by `CLAUDE.md`, with no auto-fixes and **zero new diagnostics relative to the Phase 0 baseline**. + + Amended 2026-08-04 after Phase 0 baseline capture. The absolute `EXIT_CODE: 0` form of this criterion is not reachable in this checkout for reasons unrelated to bug #418: the VSTO runtime assemblies `Microsoft.Office.Tools.Outlook.v4.0.Utilities` and `Microsoft.Office.Tools.Common.v4.0.Utilities` (`Version=10.0.0.0`, `PublicKeyToken=b03f5f7f11d50a3a`) are not installed, producing `MSB3245` and four `CS0234` errors in `TaskMaster/ThisAddIn.Designer.cs`. The recorded baselines are 4 errors / 44 warnings for the analyzer build and 5 errors / 5 warnings for the nullable build, and every error is confined to `TaskMaster/TaskMaster.csproj` — none originates in `SVGControl` or `SVGControl.Test`. Installing the Office Developer Tools component is a machine-level change outside the scope of this bug fix, so the criterion is measured relatively here and the absolute gate is enforced by CI on the pull request, where the toolchain is complete. Evidence: `evidence/baseline/analyzer-build.2026-08-04T14-36.md` and `evidence/baseline/nullable-build.2026-08-04T14-36.md`. +- [ ] **AC-7 — Underlying failure identified in writing.** A research artifact under this feature's `research/` directory names the exception thrown by `SvgDocument.Open` for `Defaults.GetDefault.SvgImage`, identifies the host(s) in which it reproduces, and states whether the existing `AssemblyResolve` fallback at `SVGControl/SvgRenderer.cs:36-104` is reached in the failing host. Delivered by `research/2026-08-04T15-05-svg-renderer-null-document-research.md`, which establishes: `Svg 3.4.7` binds `ExCSS, Version=4.2.3.0` while only `4.3.1.0` is deployed; the WinForms designer loads `SVGControl.dll` into `devenv.exe`, whose configuration carries no ExCSS redirect; the fallback is reached but returns `null` because `Assembly.Load` probes the Visual Studio directory rather than the directory containing `SVGControl.dll`; and production is a VSTO add-in inside `OUTLOOK.EXE` whose per-add-in AppDomain redirects correctly, so production does not reproduce. +- [ ] **AC-8 — `AssemblyResolve` fallback resolves from the assembly's own directory.** The fallback at `SVGControl/SvgRenderer.cs:44-104` gains a directory-probing strategy that attempts `Assembly.LoadFrom` against ordered candidate directories derived from the already-loaded `SVGControl` assembly (`Assembly.Location` directory, `CodeBase` directory, then `AppDomain.CurrentDomain.BaseDirectory`), so a same-key assembly deployed next to `SVGControl.dll` is found in a host that does not apply the project binding redirects. The implementation tolerates an empty `Location` (byte-array or shadow-copied loads) without throwing, preserves the existing re-entrance guard, and preserves the existing public-key-token match requirement. +- [ ] **AC-9 — `SVGControl.Test` builds and runs.** Decided 2026-08-04: repair the test project in this change. `SVGControl.Test` is added to `TaskMaster.sln`, its five pinned packages (`Castle.Core 5.1.1`, `FluentAssertions 6.12.0`, `Moq 4.20.69`, `MSTest.TestAdapter 3.1.1`, `MSTest.TestFramework 3.1.1`) are restored under `packages/`, and the hard MSBuild `<Error>` at `SVGControl.Test/SVGControl.Test.csproj:158-170` no longer fires. The project compiles and its tests execute under `vstest.console.exe`. +- [ ] **AC-10 — Incorrect ExCSS redirect in the test config is corrected.** `SVGControl.Test/app.config:23` currently redirects ExCSS to `newVersion="4.2.4.0"`, a version that exists nowhere in the repository, while all sixteen sibling configs use `4.3.1.0`. It is corrected to `4.3.1.0` so the test host can resolve ExCSS through the binding redirect rather than depending on the `AssemblyResolve` fallback to mask it. +- [ ] **AC-11 — Designer load verified by the documented human step.** The runbook recorded under this feature's `runbooks/` directory is executed and its evidence captured: opening `UtilitiesCS/Dialogs/MyBoxViewer.cs` in the Visual Studio WinForms designer after the fix loads the form without a `NullReferenceException`. Per the research artifact's favourable sequencing, the same capture supplies the observed exception identity for AC-7 if the bind still fails, because the fix stops discarding the exception. This criterion is satisfied by attaching the human-captured evidence to the feature folder. + +## Proposed Fix / Validation Ideas + +- [ ] Unit coverage areas: `SvgRenderer.GetSvgDocument` success and failure paths; the byte-array `SvgRenderer` constructors on malformed input; `SvgImageSelector.SetDefaultImage`; round-trip parse of `Defaults.GetDefault.SvgImage`. `SVGControl.Test` currently contains no coverage for any of these. +- [ ] Integration scenario to retest: designer-time construction path `MyBoxViewer` -> `PictureBoxSVG` -> `SvgImageSelector` -> `SvgRenderer`. +- [ ] Manual verification notes: confirm the WinForms designer loads `MyBoxViewer` without exception after the fix. + +## Next Step + +- [x] Promote to GitHub issue (bug-report template) +- [x] Move to active fix folder / branch diff --git a/docs/features/active/2026-08-04-svg-renderer-null-document-nre-418/plan.2026-08-04T14-36.md b/docs/features/active/2026-08-04-svg-renderer-null-document-nre-418/plan.2026-08-04T14-36.md new file mode 100644 index 000000000..3f4a02eff --- /dev/null +++ b/docs/features/active/2026-08-04-svg-renderer-null-document-nre-418/plan.2026-08-04T14-36.md @@ -0,0 +1,299 @@ +# svg-renderer-null-document-nre — Plan + +- **Issue:** #418 +- **Parent (optional):** none +- **Owner:** drmoisan +- **Last Updated:** 2026-08-04T14-36 +- **Status:** Draft +- **Version:** 0.3 (revision pass 1 — applies six blocking and seven non-blocking preflight findings) +- **Work Mode:** `minor-audit` (persisted marker `- Work Mode: minor-audit` in `issue.md`) +- **Language in scope:** C# only + +**Fail-closed evidence rule:** Include explicit baseline artifact tasks, final-QC artifact tasks, and coverage-comparison tasks.

These are unrelated to ExCSS, are correct as written, and must not be touched by task P1-T2. + +## Design Decisions Fixed by This Plan + +These are settled before execution so that no task requires interpretation. + +1. **Failure mode is degrade-and-log, not throw from the constructor.** AC-3 is explicit: the byte-array `SvgRenderer` constructors must not throw. They leave `_doc` null and initialize `_original` to `Size.Empty`. +2. **Dual diagnostic channel.** Every parse-failure diagnostic is written both through the existing `log4net.ILog logger` field (`SVGControl/SvgRenderer.cs:20-22`) at error level **and** through `System.Diagnostics.Trace.TraceError`, because there is no evidence a `log4net` appender is configured inside `devenv.exe`. Both channels carry the exception type and message. +3. **Fail-fast API shape.** Two new members on `SvgRenderer`: + - `public static bool TryGetSvgDocument(byte[] file, out SvgDocument document, out Exception error)` — the `Try`-style member that surfaces the captured exception (AC-4). + - `public static SvgDocument GetSvgDocumentOrThrow(byte[] file)` — throws `InvalidOperationException` whose `InnerException` is the original exception from `SvgDocument.Open` when one exists, and whose `InnerException` is `null` for the element-free path where `SvgDocument.Open` returns `null` without throwing (AC-5's stated asymmetry). + - `public static SvgDocument GetSvgDocument(byte[] file)` keeps its existing tolerant `null`-returning contract and contains **no** `catch` block of its own; it delegates to `TryGetSvgDocument`. +4. **Single catch site.** All exception handling for the parse path lives in one `catch (Exception)` inside the seam-bearing `TryGetSvgDocument` overload. It logs on both channels and returns `false` with the exception in `error`, which is a result the caller is required to inspect (AC-2). +5. **Seam.** The smallest seam per `.claude/rules/csharp.md` DI Seams: an `internal static bool TryGetSvgDocument(byte[] file, Func<byte[], SvgDocument> parse, out SvgDocument document, out Exception error)` overload. Production supplies `SvgRenderer.OpenFromBytes`. No mutable static hook is introduced, so no test mutates global state. Plain malformed bytes and `Array.Empty<byte>()` are used wherever they already exercise the path; the seam is used only to assert exact `InnerException` identity. +6. **`AssemblyResolve` strategy order is 1 → 2 → 3.** Strategy 1 (already-loaded scan) and strategy 2 (`Assembly.Load` by simple name) are preserved unchanged in behavior and order, per research §4.4's instruction to prefer an already-loaded match. Strategy 3 (directory probing with `Assembly.LoadFrom`) is new and runs after strategy 2 inside the same re-entrance-guarded region. +7. **New test files require csproj wiring.** `SVGControl.Test.csproj` uses `packages.config` and explicit `<Compile Include>` items with no glob. Every new `.cs` file must be added to the `<ItemGroup>` at `SVGControl.Test/SVGControl.Test.csproj:61-82` or it will not compile. +8. **`SVGControl.Test` needs a direct compile-time `Svg` reference.** `SVGControl.Test.csproj:122-151` contains no `<Reference Include="Svg" ...>` and `SVGControl.Test/packages.config` has no `Svg` entry; the only path to `SVGControl` is the `ProjectReference` at `SVGControl.Test/SVGControl.Test.csproj:84-87`. Because this is a legacy non-SDK project, transitive assembly references do not flow to the compiler — they land in `ReferenceDependencyPaths` (copy-local), not `ReferencePath`. Every planned test names `SvgDocument` (task P1-T8 asserts `renderer.Document` is null, typed `SvgDocument` at `SVGControl/SvgRenderer.cs:218`; task P1-T20 declares `Mock<Func<byte[], SvgDocument>>`; task P1-T21 assigns `SvgRenderer.Document = null`), so without the direct reference the tests fail to compile with `CS0012` for `Svg, Version=3.4.0.0, PublicKeyToken=12a0bac221edeae2`. Task P1-T4 adds it. +9. **AC-4's "public API" is assembly-internal by design.** `SvgRenderer` is declared `internal class` at `SVGControl/SvgRenderer.cs:18`, reachable only from within `SVGControl` and, via `InternalsVisibleTo`, from `SVGControl.Test`. The `public static` modifiers on `TryGetSvgDocument` / `GetSvgDocumentOrThrow` / `GetSvgDocument` therefore describe the type-internal surface, not a cross-assembly public surface. This is deliberate and is not a defect to remediate; task P1-T24 must state it explicitly when checking off AC-4. + +## Evidence Location Invariant + +All evidence artifacts produced by this plan are written under +`docs/features/active/2026-08-04-svg-renderer-null-document-nre-418/evidence/<kind>/`. +`artifacts/`-rooted evidence paths are forbidden and are blocked by the +`.claude/hooks/enforce-evidence-locations.ps1` PreToolUse hook.

Q1 — Mechanism + +### 2.1 Conclusion + +**Confirmed, with one refinement and one correction.** + +`SvgDocument.Open<SvgDocument>` fails because the CLR cannot satisfy `Svg`'s reference to `ExCSS, Version=4.2.3.0` in any host that does not apply a binding redirect covering that request. `GetSvgDocument` catches the resulting exception and returns `null`, and the constructor at `SVGControl/SvgRenderer.cs:138` dereferences it. + +**Exception type concluded: `System.IO.FileNotFoundException`.** + +Message shape (reconstructed from the standard .NET Framework binder message; the exact text was not captured in this session — **[INFERRED]**): + +``` +System.IO.FileNotFoundException: Could not load file or assembly +'ExCSS, Version=4.2.3.0, Culture=neutral, PublicKeyToken=bdbe16be9b936b9a' +or one of its dependencies. The system cannot find the file specified. +``` + +Evidence for `FileNotFoundException` rather than `FileLoadException`: + +- The prior author recorded exactly this type in an in-file comment at `SVGControl/SvgRenderer.cs:24-31`: "SvgDocument.Open throws FileNotFoundException for ExCSS 4.2.3." That comment was written by someone who had the failure in front of them. **[VERIFIED as a repository claim; not independently re-observed.]** +- .NET Framework appbase probing rejects a ref/def-mismatched candidate and continues probing; when probing is exhausted with no match, the binder raises `AssemblyResolve` and then throws `FileNotFoundException`. `FileLoadException` (HRESULT `0x80131040`, "The located assembly's manifest definition does not match the assembly reference") is the outcome when the assembly is bound through an explicit `<codeBase>` hint or is already loaded in the AppDomain under a conflicting identity — neither applies here. **[INFERRED from documented binder behavior.]** + +A fix must not depend on the distinction. Both `FileNotFoundException` and `FileLoadException` derive from `System.IO.IOException`, and the parse path can also produce `System.Xml.XmlException`, `TypeInitializationException`, and `ArgumentException`. The correct contract is "catch broadly, log, and rethrow wrapped", not "catch a specific binder exception type". + +### 2.2 Refinement — the failure is a JIT-time assembly load, not a runtime CSS parse + +The ExCSS reference sits inside the `if (styles.Any())` branch, but the .NET Framework JIT compiles the whole method body when the method is first invoked, resolving the metadata tokens for `newobj StylesheetParser` and the `Stylesheet` local regardless of which branch executes. The assembly load therefore occurs when `Create<T>(XmlReader, string)` is JIT-compiled, not when the branch is taken. **[INFERRED from CLR JIT semantics; not empirically confirmed.]** + +**This eliminates an otherwise attractive fix direction.** Rewriting `Defaults.GetDefault.SvgImage` to drop its `<style>` element and inline presentation attributes would make `styles.Any()` false but would **not** prevent the ExCSS bind, because the bind happens at JIT time. The planner should not pursue that direction without first disproving this inference (see § 9.3 for the verification step). + +### 2.3 Correction to the issue text + +The issue's Actual Behavior section states the exception "is unavailable because `GetSvgDocument` catches `Exception`". That is correct but incomplete. There is a second, exception-free route to `null`: an SVG payload containing no XML elements returns `null` from `SvgDocument.Open` with nothing thrown (§ 1.4). The fix must handle both, and AC-3's inner-exception requirement can only be met for the throwing route. + +--- + +## 3. Q2 — Host Matrix + +The decisive variable is which configuration file the CLR uses for the AppDomain in which `SVGControl.dll` executes, since that file determines whether the `ExCSS 4.2.3.0 → 4.3.1.0` redirect is applied. + +### 3.1 Correction to the question's premise + +There is no `TaskMaster.exe`. `TaskMaster/TaskMaster.csproj:21,25` **[VERIFIED]**: + +``` +<ProjectTypeGuids>{BAA0C2D2-18E2-41B9-852F-F413020CAA33};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids> +<OutputType>Library</OutputType> +``` + +`{BAA0C2D2-…}` is the Office/VSTO project type. Production is a VSTO add-in DLL hosted inside `OUTLOOK.EXE`. The VSTO runtime creates a dedicated AppDomain per add-in and sets `AppDomainSetup.ConfigurationFile` to the deployed `TaskMaster.dll.config`, which is why the add-in's own redirects apply even though the process config is `outlook.exe.config`. **[INFERRED from the project type plus documented VSTO AppDomain behavior; not observed.]** + +### 3.2 Host matrix + +| Host | Config file governing the AppDomain | ExCSS redirect applied? | Reproduces? | Basis | +|---|---|---|---|---| +| **WinForms designer** — `devenv.exe`, legacy in-process designer (net481 project, so not `DesignToolsServer.exe`) | `devenv.exe.config` (Visual Studio install dir) | **No** — no ExCSS entry exists there, and the file is outside the repository | **Yes** | [INFERRED] | +| **`vstest.console.exe` test host** — `testhost.exe`/`testhost.x86.exe` with a per-source AppDomain | `SVGControl.Test.dll.config` (generated from `SVGControl.Test/app.config`) | **Applied, but the redirect is wrong** — see § 3.3 | **Would reproduce but for the `AssemblyResolve` fallback** | [VERIFIED config + INFERRED host behavior] | +| **Production add-in** — `OUTLOOK.EXE`, VSTO AppDomain | `TaskMaster.dll.config` (from `TaskMaster/app.config:81-83`, `newVersion="4.3.1.0"`) | **Yes** | **No** | [VERIFIED config + INFERRED host behavior] | + +### 3.3 New finding — `SVGControl.Test/app.config` carries a broken ExCSS redirect + +`SVGControl.Test/app.config:21-24` **[VERIFIED]**: + +```xml +<dependentAssembly> + <assemblyIdentity name="ExCSS" publicKeyToken="bdbe16be9b936b9a" culture="neutral" /> + <bindingRedirect oldVersion="0.0.0.0-4.2.4.0" newVersion="4.2.4.0" /> +</dependentAssembly> +``` + +`newVersion="4.2.4.0"` names a version that does not exist anywhere on disk.

The redirect converts a resolvable request into an unresolvable one. **[VERIFIED as a config fact; the runtime consequence is [INFERRED].]** + +The reason this does not currently surface as a test failure is that no test in `SVGControl.Test` exercises `SvgRenderer` (§ 8.1), and the `AssemblyResolve` fallback added in `0b4c5c43` masks the redirect (§ 4.3). It is a live trap for the first test that touches this code — which is exactly what AC-1 and AC-5 require. + +--- + +## 4. Q3 — Why the `AssemblyResolve` Fallback Does Not Rescue the Designer + +### 4.1 The handler is reached + +`SVGControl/SvgRenderer.cs:36-42` installs the handler from the static constructor. **[VERIFIED]** The static constructor runs before the first instance constructor body executes. Loading the `SvgRenderer` type requires resolving the `SvgDocument` field type, which loads `Svg.dll`, but `Svg.dll`'s ExCSS reference is not materialised until `Create<T>` is JIT-compiled inside `SvgDocument.Open` — strictly after the static constructor has completed. The handler is therefore installed before the failing bind. **[INFERRED from CLR type-initialisation and lazy-assembly-load ordering.]** + +Answering the AC-7 sub-question directly: **the fallback at `SVGControl/SvgRenderer.cs:36-104` is reached in the failing host. It is reached and returns `null`.** + +### 4.2 Strategy 1 cannot succeed on a first load + +`SVGControl/SvgRenderer.cs:51-69` scans `AppDomain.CurrentDomain.GetAssemblies()` for a loaded assembly with simple name `ExCSS` and a matching public key token. The failing request *is* the first attempt to load ExCSS into the AppDomain, so no ExCSS assembly is loaded when the handler runs. Strategy 1 finds nothing. + +This is host-independent: strategy 1 can only succeed when some other code path has already loaded ExCSS 4.3.1 by a matching reference. In the test host, `SVGControl.Test.csproj` has no ExCSS reference at all **[VERIFIED — the `<Reference>` list at lines 122-152 contains no ExCSS entry]**, so nothing pre-loads it. **Confirmed.** + +### 4.3 Strategy 2 resolves against the wrong probing path + +`SVGControl/SvgRenderer.cs:83-92`: + +```csharp +var byName = System.Reflection.Assembly.Load(new System.Reflection.AssemblyName(requested.Name)); +``` + +`Assembly.Load` binds against the **current AppDomain's** `ApplicationBase` and `PrivateBinPath`, not against the directory the calling assembly was loaded from. The hypothesis under evaluation is therefore **confirmed**: + +- **Test host** — the AppDomain's `ApplicationBase` is the test source directory, which contains `ExCSS.dll` (copied transitively from the `SVGControl` project reference). A partial-name bind carries no version, so no `<bindingRedirect>` version range applies to it, and the binder returns whatever `ExCSS.dll` it probes up — 4.3.1.0. The public key token matches, the handler returns the assembly, and the CLR accepts it as satisfying the 4.2.3.0 request (values returned from `AssemblyResolve` bypass version checking). **This is why the test host currently works, and it is also why the broken `4.2.4.0` redirect in § 3.3 is invisible.** **[INFERRED; the copy of `ExCSS.dll` into `SVGControl.Test/bin/Debug/` could not be verified because that directory does not exist in the working tree.]** +- **Designer host** — the AppDomain is `devenv.exe`'s, whose `ApplicationBase` is the Visual Studio IDE directory. `ExCSS.dll` is not there. `Assembly.Load` fails, the nested `AssemblyResolve` it raises is short-circuited by the re-entrance guard at lines 76-80 (which correctly returns `null` to prevent recursion), the `catch` at lines 94-97 swallows the failure, and the handler returns `null` at line 103. The original `FileNotFoundException` propagates into `SvgDocument.Open`, is caught by `GetSvgDocument`, and becomes the `NullReferenceException`. **Confirmed. [INFERRED from binder semantics and the code as written.]** + +### 4.4 What the fallback would have to do instead + +The handler must resolve relative to the **location of the requesting assembly**, not the host's probing path. The direction (not a full implementation) is: + +1. Build an ordered candidate-directory list rather than a single directory: + - `Path.GetDirectoryName(typeof(SvgRenderer).Assembly.Location)` when `Location` is non-empty; + - the directory derived from `typeof(SvgRenderer).Assembly.CodeBase` (convert the `file://` URI) — this survives some cases where `Location` is unhelpful; + - `AppDomain.CurrentDomain.BaseDirectory` as a last resort. +2. For each candidate, probe for `<simpleName>.dll` and load the first hit with `Assembly.LoadFrom`. +3. Keep the existing public-key-token equality check on the loaded result before returning it. +4. Keep the existing re-entrance guard. + +**Risks the planner must weigh:** + +- **`Location` is empty for byte-array loads.** `Assembly.Load(byte[])` produces an assembly whose `Location` is `""`. Visual Studio's designer type-resolution service has historically used `Assembly.LoadFrom` against a shadow-copy directory under `%LOCALAPPDATA%\Microsoft\VisualStudio\<ver>\ProjectAssemblies\<hash>\`, which yields a non-empty `Location` — but whether `ExCSS.dll` is present in that shadow directory alongside `SVGControl.dll` is **[UNVERIFIED]**. If VS shadow-copies only the assemblies it explicitly resolves, `ExCSS.dll` should be there because it is an explicit `<Reference>` in both `SVGControl.csproj:57` and `UtilitiesCS.csproj:67`. This must be confirmed empirically before the fix is declared to close AC-8. +- **`LoadFrom` context divergence.** An assembly loaded via `Assembly.LoadFrom` enters the LoadFrom context. If the same ExCSS assembly is later bound into the default context by a different code path, the CLR can end up with two distinct type identities for the same types, producing `InvalidCastException` at the boundary. In practice the risk is low when the `LoadFrom` path is the same file the default binder would have found, because the CLR matches on identity, but the risk is real in the designer where the shadow-copy path is not the default probing path. `UtilitiesCS` references ExCSS 4.3.1 directly, so a second default-context bind is plausible. The planner should document this and prefer returning an already-loaded match (strategy 1) whenever one exists — the existing code already does this, and that ordering should be preserved. +- **Empty-candidate fallthrough.** If no candidate directory yields the file, the handler must still return `null` so other resolvers and default resolution can run. It must not throw from inside an `AssemblyResolve` handler. + +### 4.5 Constraint the fix must satisfy regardless of approach + +Even a perfect `AssemblyResolve` fallback is a mitigation, not a guarantee, because it depends on host-specific probing behavior that the repository does not control. AC-3 (a diagnosable exception instead of an NRE) is the only part of the remedy that is fully within repository control and is host-independent. It should be treated as the primary deliverable; the binding remedy is secondary. + +--- + +## 5. Q4 — Fizzler Redirect Defect + +### 5.1 Classification: **(b) latent defect, currently inert** + +- Nothing in the deployed dependency graph requests Fizzler. `Grep Fizzler SVGControl/bin/Debug` returned exactly one match, in `SVGControl.dll.config` — i.e. in the redirect itself, not in any assembly's metadata. **[VERIFIED]** +- `ExCSS 4.3.1` does not reference Fizzler. **[GIVEN]** +- `Svg 3.4.7` does not reference Fizzler (its CSS selector work goes through ExCSS `StylesheetParser`; the `Fizzler` string is absent from `Svg.dll`). **[VERIFIED]** +- `SVGControl/PictureBoxSVG.cs:14` has an unused `using Fizzler;` directive, which produces no `AssemblyRef` row. **[VERIFIED]** +- `Fizzler.dll` (1.3.1.0) is nonetheless deployed because `SVGControl.csproj:60-62` and `UtilitiesCS.csproj:70` declare explicit `<Reference>` items with `HintPath`s. **[VERIFIED]** + +It is **not** an active contributor to issue #418.
