I plan to include some kind of GUI into one of my recent OpenTK projects and I selected a C# port of the Gwen GUI framework (https://code.google.com/p/gwen-dotnet/). I downloaded the latest snapshot and tried out the OpenTK Sample. I noticed that the included renderer is drawing quads and is using now deprecated vertex arrays. Since my project is targeting OpenGL version 4.3 I can't really use the OpenTK Renderer included in the project without a fair bit of modification.
Does anybody know if there is already a more modern renderer that works well with newer OpenGL versions? Right now, I am working on a version that is using VBOs, but if there already exists a more "convenient" option, I'd be very grateful if you could point that out to me.
Thanks and greetings
