Shader compilation failed when implementing IComputeShader interface in a different way.

[HoneyFox]

Reproduction Steps

When writing a compute shader, use void IComputeShader.Execute() instead of public void Execute().

Expected Behavior

The shader should be compiled normally as if public void Execute() is used.

Actual Behavior

The compute shader cannot be compiled. Error reports as follows:

"The DXC compiler encountered one or more errors while trying to compile the shader: "error: expected external declaration [NumThreads(__GroupSize__get_X, __GroupSize__get_Y, __GroupSize__get_Z)] .". Make sure to only be using supported features by checking the README file in the ComputeSharp repository: https://github.com/Sergio0694/ComputeSharp. If you're sure that your C# shader code is valid, please open an issue an include a working repro and this error message."

System info

ComputeSharp 3.0.1
Windows 10
Visual Studio 2022 17.11.4, .NET 8.0

It's not really a serious issue after all, just might be confusing for new users.

Ah, yeah agreed it'd be nice to support this scenario too, thank you for opening this! 🙂
