From a7eb65b733fa7630f3f6f83dec3d3feecf9ebe27 Mon Sep 17 00:00:00 2001 From: Rolling2405 <223556219+Copilot@users.noreply.github.com> Date: Thu, 30 Apr 2026 20:39:30 -0700 Subject: [PATCH 1/5] Add net10.0 target framework and update CI Adds .NET 10 to library and test multi-targets while preserving netstandard2.0 (library) and net8.0 (tests). Fixes packaging icon declaration to use (was ) so it resolves correctly under multi-targeting on newer SDKs. Workflow: - Bump actions/checkout v3 -> v4 - Bump actions/setup-dotnet v3 -> v4 - Add 10.0.x to dotnet-version (alongside 3.1.x and 8.0.x) Verified locally: 353 passed (2 skipped) on both net8.0 and net10.0.

Changes ------- sources/NetArchTest/NetArchTest.csproj - Add net10.0 TFM alongside existing netstandard2.0 - Add IsTrimmable/IsAotCompatible guards (NET10_0_OR_GREATER only) sources/NetArchTest/NetArchTestAotMessages.cs (new) - Shared const message strings used by all Requires* attributes sources/NetArchTest/Condition_Dependencies.cs sources/NetArchTest/Predicate_Dependencies.cs sources/NetArchTest/Slices/SliceCondition.cs sources/NetArchTest/Functions/FunctionDelegates_Dependencies.cs - [RequiresUnreferencedCode] + [RequiresDynamicCode] on every public/internal method that drives the dependency-search pipeline (Tier 2 surface) sources/NetArchTest/Dependencies/TypeParser.cs - Type-level [UnconditionalSuppressMessage] for IL2057/IL2077/IL2080 covering Mono.Cecil private-field reflection in the static cctor - [RequiresUnreferencedCode] + [RequiresDynamicCode] on Parse() and ParseReflectionNameToRuntimeName() sources/NetArchTest/Dependencies/DataStructures/NamespaceTree.cs - Extract parseNames=true branch into private ParseTokensRequiringReflection() annotated with Requires*; Add() gets [UnconditionalSuppressMessage] with justification (runtime-guarded; Tier 1 callers pass false) sources/NetArchTest/Extensions/Mono.Cecil/TypeDefinitionExtensions.cs - [RequiresUnreferencedCode] + [RequiresDynamicCode] on ToType() sources/NetArchTest/Assemblies/PublicUse/TypeContainer.cs - Extract Lazy initialiser lambda into private ResolveReflectionType() annotated with Requires*; constructor gets [UnconditionalSuppressMessage] (Tier 1 paths never read ReflectionType) tests/NetArchTest.AotSmoke/ (new) - NativeAOT publish smoke that exercises Tier 1 only (Types.FromPath + name/namespace/structural predicates) - PublishAot=true, TreatWarningsAsErrors=true, NoWarn IL2104 (Mono.Cecil 0.11.x is not trim-annotated upstream — IL2104 is its aggregate warning; Tier 2 callers still get the proper annotations at their call sites) - Prints 'OK' and exits 0 when the AOT image is correct tests/NetArchTest.AotSmoke.Fixture/ (new) - Minimal test-assembly DLL published alongside the smoke binary Result: dotnet publish -r win-x64 -c Release produces a 4.3 MB native exe with zero IL warnings and zero errors; the exe prints 'OK' and exits 0. All 353x2 unit tests continue to pass.
