Sorry, just to clarify a few points:

- You're using WSL, right? Is it WSL 1 or 2?
- You can run other GUI applications on WSL.
- Which Linux distribution are you using?

- version 2
- yes, i'm configured Xming and check this on default x11 programs - xcalc, xclock and firefox
- Ubuntu 20.04.3 LTS (GNU/Linux x86_64)

Another question: Are you able to run OpenGL applications, such as glxgears?

I've been able to run our samples using WSL2 and our 3.1.1 NuGet packages.

However, even though it worked for me, I've made two changes that will be part of the next release:

- We were passing "" as an argument to XOpenDisplay. I've changed the parameter to null. When a null pointer is passed to XOpendDisplay it uses the value of the DISPLAY environment variable. It is working for me using "", but the new code is more correct.
- I've made changes to the OpenGL/GLX/X11 DllImports to explicitly state the version of the so, so that you don't need, just and so on. I could get around this by creating the symlinks, but it's more correct this way.

I didn't see any problems with Noesis_GetCurrentThreadId. The version of has those functions and they work correctly.
