SDL + Winforms in one Application

Hello, we have a .NET/C# application that has SDL windows and System.Windows.Forms windows in the same process. The Winforms Application.Idle event calls the ProcessEvents of SDL.

We are experiencing missing keyboard events. Specifically, Text events don’t seem to come thru.

Is there any configuration we might be missing? Or is it impossible by definition to have those two event loops in the same application? Or should we do something else in a different way?

Thanks for any tips!
