Initialize Bindings

[Fabi12345]

Hi
I get a runtime error when I run the Testform, it says you need to initialize the OpenGL binding first by calling LoadBindings().
Here is the full message:

System.InvalidOperationException: You need to initialize the OpenGL binding first by calling LoadBindings() or creating a compatible OpenGL window.

I also have a project which I updated from 3.3.3.0 to 4.0.0.0 and got the same issue.

Windows 10
Radeon RX 580
AMD Ryzen Threadripper 1920X 12-Core Processor 3.50 GHz
Tag 4.0.1 (compiled and unmodified)

[NogginBops]

What version of the GLControl are you using? How are you running the code?

[Fabi12345]

I tried the two latest tags 4.0.0 and 4.0.1, same result.
Compiled and run in Visual studio 2022, but also tried the bash file with .nuke.
I tried different configurations of the profile and API in the designer form...with no effect.

[Fabi12345]

When in the glControl_Load(), the glControl.Context is still null, I think this is troublesome.

Bindingcontext is set somehow, but maybe it should bind to OptenTK.IBindingsContext and not System.Windows.Forms.BindingContext, that's at least what it says when I try to bind it manually, cannot convert.
