An alternate take on the RemoteExecutor used in the dotnet/runtime unit tests. Instead of using reflection, it uses a source generator to register available remote method and to expose strongly-typed wrapper for executing them.

There is also a goal to make this all work for all of these app models:

• .NET Framework: executor is an EXE that is directly executable by the OS
• .NET Core: use the app host (dotnet.exe) to load and execute the executor DLL
• SingleFile: the .NET Core model, but packaged into a single EXE
• NativeAOT: compiled ahead-of-time into a single native EXE

Currently, it does work across all of those models. But you have to set the OutputType of RemoteExecutorLib to Exe to work with the first two.
