How should I create imgui correctly and correctly ?

[Perksey]

Ensure the version of ImGui.NET you're using matches the version Silk.NET is using

[Perksey]

Try rebuilding your project (cleaning out bin/obj)

[qian-o]

I cleaned up all the content, but the error still exists.

[Perksey]

We’ve had another report of this, I have genuinely no idea what’s causing this. If someone can investigate this it’d be much appreciated.

ImGuiNET/ImGui.NET#412

I think the problem lies in ImGui.NET, but I'm not sure how to solve it.

[Perksey]

Yes, I've just vented here: ImGuiNET/ImGui.NET#436
I recommend that you do the same to increase visibility.

[qian-o]

Okay, I will

I think the problem lies in ImGui.NET, but I'm not sure how to solve it.

A temporary solution you could do on your end, would be copying the ImGuiController code into your project, its a hack, but should make it work. A fix could be done on either side here, whether it be done by us through multi-targetting frameworks and providing a NS2.1 version of out ImGuiControllers (so that NuGet grabs the correct one) and pushing out a hotfix, or pushing out a hotfix once ImGui.NET fixes this issue upstream
