Rendering Context MakeCurrent Doesn't Work From Other Threads

[BBoldenow]

Sorry, I can't get to Discord via work, hopefully this is the right place to post -

Currently MakeCurrent doesn't work from other threads for rendering contexts - it throws a resource in use exception. This seems like it'd be worthwhile so you can spawn threads for texture loading and the like that can subsequently request the context. If there is a way to do this currently feel free to let me know (or if there's a better place to post requests).

This is a perfectly fine place to raise an issue. Thanks for doing so.

Can you try create a context yourself externally and pass that in as part of the settings? It should allow for all sorts of customization as required.

Hello! I have the same issue and I really need that. I have migrated to GLWpfControl from the old GLControl, which had the same issue, so I recreated the context from the other thread and it worked. However, it is not possible here to create another context from a non-interface thread. I didn't understand how I can create the context externally. Could you please give me some direction to go?
Thanks in advance.

Varon, thanks for responding. Life has been a bit crazy, but I'll give that a shot and let you know how it goes. Thanks again!

Make sure that you are calling GraphicsContext.MakeCurrent(null) on the thread it was created to "detach" the context from its current thread.
This allowed me to use the context on another thread with no problems.

Using context sharing to create separate contexts (NativeWindows) should work fine.
For multiple GLWpfControls, #86 is going to make every GLWpfControl have it's own OpenGL context and will add a SharedContext setting so context sharing can be setup between controls.

I'm going to close this issue, feel free to reopen if this is not completely fixed.
