which version should i use currently please? thanks. @Trivaxy

hi @Perksey i had applied your changes into my logic (as the official release is not ready yet), i found that i can create NVDXInterop extension in my 'primary' context,...

so fast! thanks so much @Perksey but just had a try and it didn't work, here is the code: ```C# [MethodImpl(MethodImplOptions.AggressiveInlining)] [SupportedOSPlatform("windows")] private INativeContext CreateNativeContext() { return WGL.CreateDefaultContext(["Opengl32"]); } //...

thanks for your suggestion, i have changed my code like this: ```c# [MethodImpl(MethodImplOptions.AggressiveInlining)] private static IntPtr GetProcAddress(string proc) { var p = NativeMethods.wglGetProcAddress(proc); return p != IntPtr.Zero ? p :...
