Pull request overview

This PR scaffolds the solution structure needed for upcoming CLI introspection work by adding new library, example, benchmark, and test projects, and wiring them into the solution/build.

Changes:

• Added new library projects for CLI Schema and OpenCLI introspection scaffolding.
• Added example apps (C#, F#, Visual Basic), a BenchmarkDotNet benchmarks project, and an MSTest test project.
• Updated solution and repo-wide build/package configuration to support the new projects.

Wrong!
The SDK in use for this Project is MSTest.Sdk, which already comes with:

<ItemGroup>
  <Using Include="Microsoft.VisualStudio.TestTools.UnitTesting" />
</ItemGroup>

You only did a syntactic check of this document,
but with .NET and C#, you need to do semantic checks of the compilation.

[Flash0ver]

No!
This is a conscious structural decision:

This single Test-Project will include tests for more than one library.
So there will be an appropriate Introspection folder/namespace added once features are added to the libraries and respective tests are added here.

However, I might change my mind here, see:

• https://github.com/FlashOWare/command-line-interfaces/pull/5/files#r3778299260
• https://github.com/FlashOWare/command-line-interfaces/pull/5/files#r3778304518

When applying this change, there will be two test projects instead, one per library project.

False!
Although this Pull Request does indeed close #2,
#2 does not call out "multi-targeting" whatsoever.

[Flash0ver]

Incorrect!
The IsAotCompatible metadata is indeed emitted since net10.0.
But Native AOT deployment is already supported since net7.0, and net8.0 adds AOT analysis warnings.

See documentation:

^{https://learn.microsoft.com/dotnet/core/deploying/native-aot#target-framework-requirements}
When preparing libraries for AOT compatibility, target the latest supported TFM. This helps you benefit from the latest analyzer improvements. At a minimum, target net8.0 or later. This version is required for AOT analysis warnings.

Therefore can we only VerifyReferenceAotCompatibility since net10.0.

Rejected!
This is preparing for Unsafe evolution, starting with the upcoming C# 15, planned to be releases with C# 16. See:
