stride3d/stride — reverse-engineered prompt

I want this repo set up so I can actually use Stride from source on Windows without fighting the build. Please get the engine compiling in Visual Studio, make sure the Game Studio editor launches, and confirm the basic workflow works for creating and running a simple game project.

If there are repo specific setup steps, missing tools, large assets, or build quirks, handle those and document them in a very simple way. I would also like one quick proof that the engine is working, either by opening a sample or by generating a starter project from the CLI templates and running it successfully. If there are tests or sanity checks that are realistic to run, do the obvious ones so we know the build is healthy.

Keep the result practical for someone who wants to explore realistic rendering and maybe VR later, not just compile code. If anything in the docs has changed, look up the current Stride build instructions online and use the right approach.
