Simple Stride Game and its corresponding server that processes physics raycasts remotely.
Press space or right click to "fire" and server will check if the sphere is hit.
Make sure to run the server first, then the game.
Setting both projects as startup projects works fine too (right click on the solution -> Set Startup Projects).
Right now the server is a quick proof of concept that uses the Stride API manually to load a scene.
Later it might be easier to have a HeadlessGame type to automatize the loading of a scene without graphics API and still be able to process specific C# scripts.
