…AUDE.md Captures the compiler-matrix model, the test kinds and their pipelines, how to add tests per kind, the #if/preprocessor-symbol comparison rules, and the probe-a-construct-across-all-compilers workflow, so this no longer has to be reverse-engineered from the runners.

…ast resort Hosts without a .NET Framework installation (e.g. Linux and macOS) have no GAC; the only system-wide assembly store there is the shared-framework directory of the runtime executing the decompiler, and UniversalAssemblyResolver only consulted it through the version <= 4.0 legacy fallback. This made e.g. the type-forwards of a netstandard facade (pointing to a versioned System.Runtime) unresolvable, which left well-known types like Nullable<T> without a definition and among other things misaligned nullability decoding (Nullable<T> occupies no slot in the nullable metadata, so it must be recognized). On Windows nothing the GAC answered changes; the new fallback only adds resolutions that previously failed outright. Assisted-by: Claude:claude-fable-5:Claude Code
Compilation uses the .NET builds of the Roslyn toolsets (tasks/netcore*,
bincore csc.dll/vbc.dll launched through the dotnet host). ilasm/ildasm
options use the '-' prefix, which all platforms accept. The dotnet-hosted
compilers have no implicit references or SDK path: net40 compiles pass
mscorlib explicitly, and vbc gets -sdkpath, _MYTYPE=Empty and
-vbruntime:Microsoft.VisualBasic.Core.dll (the facade in the ref packs is
not followed for runtime helpers). The TestRunner gets a self-contained
build for the host platform.
Configurations depending on Windows-only tools or runtimes (legacy
csc/vbc, Roslyn 1.x/2.x, mcs, Force32Bit, executing net40 binaries) are
filtered from the matrix off-Windows via Tester.SupportedOnCurrentPlatform
or gated with [Platform("Win")]. PdbGen comparisons normalize document
name separators, and Correctness/Async uses Console.IsInputRedirected
instead of the Windows-only Console.CapsLock.

ICSharpCode.Decompiler.Tests/CLAUDE.md): test kinds, fixture structure, how to add tests, the#if/preprocessor-symbol comparison rules, and the compiler-matrix model.UniversalAssemblyResolvernow searches the shared-framework directory of the executing runtime as a last resort. Hosts without a .NET Framework installation have no GAC, so e.g. the type-forwards of a netstandard facade (pointing to a versionedSystem.Runtime) were unresolvable there — which among other things misaligned nullability decoding (Nullable<T>occupies no slot in the nullable metadata and must be recognized).
