Test what you ship: MSTest and Native AOT

MSTest 4.4 introduces support for publishing and running test projects as Native AOT executables, using compile-time source generation to record test classes and invocation delegates before trimming occurs. This closes a gap where managed test runs pass but the trimmed, ahead-of-time compiled application fails at runtime, for example when reflection-based JSON serialization is disabled. The guidance recommends piloting a single representative test project with Native AOT publishing alongside the existing managed test suite, tracking test-count parity as a release gate, and treating this as a complement to (not a replacement for) full end-to-end validation of the shipped artifact. Migration limitations include classes that only inherit [TestClass], ref/out/in parameters, and [AssemblyFixtureProvider] usage, which aren't yet supported in the Native AOT path.
