[WotCon] Add the WoT Connectivity registry client - #4142

Adds the client-side surface for the WoT Connectivity registry: browsing and reading registry groups, resources and versions, uploading documents through FileTransfer, and invoking the registry methods. WotRegistryClient derives from the shared XRegistryClient so the generic registry traversal is not reimplemented here, and it takes an explicit registry root so a server that hosts the registry somewhere other than the well-known location can still be used.

Reverts the temporary client-only compile exclusions so the WotCon test project keeps the existing server, provider and hosting tests from the base branch. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 9e6a5abf-3299-4cd1-9855-010fedbf0ad8

- The XML doc contains a duplicated
<param name="destinationPath">entry, which can break doc generation and IntelliSense. Remove the duplicate param line. Also, since some platform implementations (e.g.,File.Replaceon older TFMs) can fail across volumes/filesystems, it would be helpful to document any such constraints explicitly in this contract comment.

The fluent builder generator emits calls to INodeManagerBuilder.VariableFromDataTypeId and to a NodeManagerBuilder constructor overload that carries the data-type lookup, but the runtime side of that API was missing, so every generated node manager failed to compile with CS1729 and CS1061. Adds the VariableFromDataTypeId resolution to the builder interface and implementation, along with NodeStateLookupExtensions.FindByDataType, which is the lookup the builder delegates to and has no other consumer. Resolution reports BadNodeIdInvalid for a null data type, BadNodeIdUnknown when nothing matches, BadBrowseNameDuplicated when the match is ambiguous, and BadTypeMismatch when the resolved node is not a variable. An optional browse name disambiguates a data type that is carried by more than one variable.

Fixed the net10.0 solution build failure on this PR. This branch carries the The fix lands in #4132 (where the generator change belongs) and is cherry-picked here so Verified locally: |
DiNodeManager constructed NodeManagerBuilder without the data-type resolver, so
VariableFromDataTypeId reported BadNodeIdUnknown ("no predefined variable has DataType")
for every DI node manager - a misleading error, since the lookup had simply never
been supplied rather than the variable being absent.
Delegates to NodeStateLookupExtensions.FindByDataType rather than hand-rolling the
scan a fourth time in this file.

Adds the materialization runtime that turns registered WoT Thing Descriptions into live OPC UA nodes: a dependency graph over the registered documents, a coordinator that drives resolution and projection, and a binding runtime that attaches protocol channels to the projected variables. Projection runs through the NodeManager lifecycle rather than mutating a running address space in place, so a refresh either commits a complete new generation or leaves the previous one untouched. The resolver, converter, contributor and target variable seams are interfaces so a host can substitute its own document sources. Also adds the registry NodeManager that exposes the registry itself in the address space, and the hosting extensions that register the whole runtime with dependency injection.

…arcschier/wot-16-samples # Conflicts: # src/Opc.Ua.Types/Utils/FileSystem/VirtualFileSystem.cs
Adds three runnable samples: two flat OPC UA tag servers and an aggregation server that materializes them into a DI/Machinery/Pumps model through the WoT registry, plus an aggregation client that drives the result. The AggregationServer also ships a memory protocol binding, which doubles as the worked example for the binding contributor guide. Documents the WoT Connectivity surface end to end: a new protocol bindings guide, the expanded WoT Connectivity overview covering the registry, materialization and runtime projection, and the shadow-reload and shared byte-store sections for the runtime NodeSet and xRegistry guides. Registers the sample and test projects in the solution so they are built and run by CI.

The WoT registry node manager can be asked to delete its address space after the externally-owned materialization coordinator has been disposed. That disposed the coordinator semaphore before DeleteAddressSpaceAsync called RemoveAllAsync, so shutdown reported ObjectDisposedException from the node manager cleanup path. Keep coordinator cleanup available after Dispose when live projections remain, block new refreshes, and release the semaphore once the deferred cleanup has drained. Also order the direct integration-test teardown through the server fixture so the node manager cleanup runs before test-owned services are released, and add a regression test for shutting down with a live materialized projection after coordinator disposal.

During ordered server disposal, the NodeManager lifecycle has already entered shutdown before WotRegistryNodeManager deletes its address space. Removing materialized WoT projections by routing back through the lifecycle is therefore the wrong operation: the lifecycle will tear down every remaining dynamic NodeManager as part of its shutdown completion. Expose the lifecycle shutdown state and make the WoT projection host treat removal as a no-op once that state is active. Normal refresh/removal paths still unregister projections through the lifecycle, while full server teardown avoids re-entering a component that is already shutting down. The shutdown regression now exercises synchronous server disposal with active projections.

Master replaced the ambient AsyncLocal re-entrancy guard with an explicit IOperationContext parameter on the lifecycle add, reload and remove operations, so the WoT projection host no longer compiled: its cancellation token was binding to the new caller-context parameter. The host passes null, which states that these calls are not made on behalf of an executing OPC UA request. The shadow and immediate reload paths are unchanged because those overloads deliberately take no caller context; they are the reload modes that are safe to invoke from a request callback.

Merging master added an IOperationContext parameter to the NodeManager lifecycle add operation, so these tests no longer bound their argument to the intended overload. They pass null because the registration is created by the test fixture rather than on behalf of an executing request.

…ion (#4156) Adds the runnable WoT Connectivity samples and completes the documentation. This is **PR 16 of a stack** splitting #4093, and the last one. ## Samples Three projects under `samples/WotCon/`: * **FlatTagServer** — a plain OPC UA server exposing flat tags, used as an aggregation source. * **AggregationServer** — registers Thing Descriptions with the WoT registry and materializes two flat sources into a runtime-loaded DI/Machinery/Pumps Pump model. It also ships a small in-memory protocol binding, which is the worked example the binding contributor guide walks through. * **AggregationClient** — drives the aggregated model: commands, `Refresh`, monitoring, and generation replacement. ## Documentation * New `docs/WotBindings.md` — the bindings that ship today (planner/executor architecture, bundled vs separate packages, operation coverage, target mapping, lazy channels, generation lifetime) plus the contributor guide for adding your own, with diagnostics, tests, packaging, TFM, trimming and NativeAOT guidance. * Expanded `docs/WoTConnectivity.md` covering the registry, dependency-closure materialization and runtime NodeSet projection. * `docs/RuntimeNodeSets.md` gains the shadow-reload section and `docs/XRegistry.md` the shared byte-store section. Both document APIs introduced earlier in the stack; they are collected here because this is the documentation PR. * `docs/README.md` links the new pages. ## Solution registration Registers the three samples and `Opc.Ua.WotCon.Samples.Tests` in `UA.slnx` so CI actually builds and runs them. ## Stack position Sits on top of **#4154** (materialization) and additionally merges **#4142** (registry client) and **#4144** (protocol executors), because the samples exercise the whole stack — `AggregationServer` needs the OPC UA executor and the client sample needs the registry client. Its diff therefore shows their content until they land. It also carries `WotRegistryProjectionLiveTests.cs`, which #4154 deliberately left out: those tests need both the materialization runtime *and* the registry client, so this is the first branch where they compile. ## Validation * All three samples build clean on every target framework. * `Opc.Ua.WotCon.Tests`: **830 passed**, 0 failed (769 from #4154 plus 61 from the live projection tests). * `Opc.Ua.WotCon.Samples.Tests`: 6 of 7 pass locally; the remaining one fails with `CryptographicException: The system cannot find the path specified`, a known certificate-store problem on this machine that was previously reproduced against a clean baseline worktree and is not related to this change. CI will confirm. * 0 warnings, 0 errors. One fix was needed while bringing the sample across: its memory binding called `ResolveCodec` with the pre-`out WotPayloadDescriptor` signature. The API gained the payload out-parameter and a `bool` result during review of the binding PRs, so the sample now follows the same `if (!ResolveCodec(...)) return Unsupported(...)` pattern as the shipped planners. Integration PR: #4093.
…pace (#4154) PR 14 of the stacked series splitting the large WoT Connectivity integration PR #4093. This PR adds the server-side materialization runtime that turns WoT Thing Description resources from the xRegistry snapshot into OPC UA address-space projections. The coordinator builds the dependency closure for each resource, plans binding metadata, activates binding channels, and publishes the resulting projection through the registry NodeManager so refresh, retire, and reload operations remain observable and deterministic. Projection intentionally goes through the NodeManager lifecycle reload API instead of mutating live nodes directly. That keeps complex type reload, runtime NodeSet publication, shadow reload, immediate reload, and retirement on the same lifecycle path as other dynamic server address-space changes. This branch has a triple dependency. It is based on #4146 (registry), and additionally needs #4147 (lifecycle reload API) and #4128 (2-argument TryGetStructure). Both #4147 and #4128 are merged into this branch, so this PR's diff will show their content until those dependencies land.

…ation, Server and xRegistry work it builds on (#4128) ## Summary Adds OPC UA WoT Connectivity 1.1 to the stack, together with the Types, source generation, Server and xRegistry work it is built on. This branch is the merge point for the fourteen-PR stack that replaced integration PR #4093; every constituent PR was reviewed and approved separately and is listed below. 414 files changed, +108,936 / -3,199. Roughly 46k added lines of product code, 57k of tests, plus samples, tools and documentation. ## Types - Complete `ExtensionObject` raw-body decoding for binary, XML and JSON bodies by resolving the concrete type through the message context's encodeable factory, and simplify the `Variant` structure helpers by delegating to it (#4128). - Add `IAtomicFileReplace` as an optional `IFileSystem` capability so existing external implementations keep working, with atomic publish for `LocalFileSystem` via `File.Replace`/`File.Move` and for `VirtualFileSystem` by re-keying the in-memory entry (#4128). - Add lossless conversion between WoT documents and NodeSet2 (`Opc.Ua.Wot.WotNodeSetConverter`). A byte-exact `uav:nodeSet` envelope is preserved when requested, the structured `uav:nodes` projection is used when the readable vocabulary is incomplete, and NodeSet2 is otherwise synthesized from readable WoT terms. Unmapped JSON members survive a round trip as pointer-addressed residue (#4131). ## Source generation - Improve the NodeSet to ModelDesign conversion and the generated node state (#4132). - Generate OPC UA models directly from WoT Thing Description files (#4134). ## Server - Add live NodeManager shadow and immediate reload. A reload materializes a new generation beside the active one and switches atomically; the superseded generation is retired gracefully so existing MonitoredItems keep being served until they drain, or immediately when the caller asks for it. Includes the request admission and drain machinery that lets an orderly shutdown wait for admitted requests instead of tearing down underneath them (#4147). - Make subscription transfer between sessions transactional, so a failed transfer leaves neither session holding a partially moved subscription (#4150). ## xRegistry - Allow clients to use explicit registry roots rather than assuming a well-known location (#4130). ## WoT Connectivity - Add the WoT Connectivity 1.1 information model: a registry-first revision layered on the abstract xRegistry base model, incorporating the complete published OPC 10100-1 v1.02 surface as deprecated nodes in the same namespace so existing 1.02 clients keep working (#4139). - Add the protocol binding abstractions and planners that compile WoT forms into executable plans (#4140). - Add the HTTP, Modbus, OPC UA and MQTT binding executors (#4144). - Add the registry and its stores, including document versioning, validation, dependency resolution and refresh (#4146). - Add the registry client (#4142). - Materialize WoT Thing Descriptions into the server address space, deriving types from Thing Models and instances from Thing Descriptions (#4154). - Restore the WoT asset registry bridge so the deprecated 1.02 asset surface is backed by the registry (#4171). - Add the WoT Connectivity samples and complete the documentation (#4156), and restore the remaining coverage and docs (#4172). ## New projects `src/Opc.Ua.WotCon.Bindings`, `src/Opc.Ua.WotCon.Bindings.Mqtt`, `tests/Opc.Ua.WotCon.Bindings.Tests`, `tests/Opc.Ua.WotCon.Samples.Tests`, and the `samples/WotCon` AggregationServer, AggregationClient and FlatTagServer samples. ## Constituent pull requests Merged into this branch top-down, each independently approved: | PR | Title | | --- | --- | | #4128 | [Types] Complete ExtensionObject decoding and add an atomic file replace capability | | #4131 | [Types] Add lossless conversion between WoT documents and NodeSet2 | | #4132 | [SourceGeneration] Improve NodeSet to ModelDesign conversion and generated node state | | #4134 | [SourceGeneration] Generate OPC UA models from WoT Thing Description files | | #4147 | [Server] Add live NodeManager shadow and immediate reload | | #4150 | [Server] Make subscription transfer between sessions transactional | | #4130 | [XRegistry] Allow clients to use explicit registry roots | | #4139 | [WotCon] Add the WoT Connectivity 1.1 information model | | #4140 | [WotCon] Add the WoT protocol binding abstractions and planners | | #4144 | [WotCon] Add the HTTP, Modbus, OPC UA and MQTT binding executors | | #4146 | [WotCon] Add the WoT Connectivity registry and its stores | | #4142 | [WotCon] Add the WoT Connectivity registry client | | #4154 | [WotCon] Materialize WoT Thing Descriptions into the server address space | | #4156 | [WotCon] Add the WoT Connectivity samples and complete the documentation | | #4171 | Restore WoT asset registry bridge | | #4172 | Restore WoT coverage and docs | Supersedes #4093. ## Follow-up The WoT Connectivity and WoT Binding drafts have moved to 1.1-draft2 since this work was authored. Aligning with that revision - the removed group vocabulary, the new projection/View construct, the remaining model vocabulary terms and the two new portable-identity validation rules - is tracked separately and will follow in its own pull request. ## Validation Built for every target framework with zero warnings and zero errors, and validated at the tip of the stack with `Opc.Ua.WotCon.Tests` at 999 passed / 0 failed and `Opc.Ua.Server.Tests` at 4024 passed / 0 failed. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 9e6a5abf-3299-4cd1-9855-010fedbf0ad8

PR 15 of a stacked split of integration PR #4093 into independently reviewable pieces.
This branch is stacked on #4139 (
marcschier/wot-10-wotcon-model) and additionally has #4128 (marcschier/wot-01-core-types) and #4130 (marcschier/wot-09-xregistry-client) merged in so this client slice can build.Those extra dependencies are intentional:
WotRegistryClient.cs:83—error CS1729: 'XRegistryClient' does not contain a constructor that takes 4 arguments.WotRegistryClient.cs:346,375andWotRegistryResourceClient.cs:144—error CS1501: No overload for method 'TryGetStructure' takes 2 arguments.The extra diff from #4128 and #4130 disappears once those PRs land.
This PR adds the WoT Connectivity registry client surface for browsing and reading registry groups, resources and versions, uploading documents through FileTransfer, invoking registry methods, and registering the client through DI/builder helpers.
