### AI overview

MSTest 4.4 uses source generation to let test projects run as Native AOT executables, helping teams test under the same trimming and deployment constraints as their applications. The article explains that this can reveal application issues such as reflection-dependent serialization that managed test runs may miss.

### Source excerpt

MSTest source generation lets test projects use the same Native AOT and trimming deployment model as the applications they validate, while reducing reflection on the test execution path. The post Test what you ship: MSTest and Native AOT appeared first on .NET Blog.
