I really want to wave the cross platform flag!
Most the stuff I read about OpenTK (OpenGL ES 2.0) for a shared project seems to be issues with it working on Android (I believe its VBO issues)
Has anyone managed to make something work in OpenTK / OpenGL that renders on iOS and Android (Windows would be nice) or is it just not worth doing.
Do people mainly use MonoGame and XNA? I have done quite a lot of iOS / Android OpenGL and just hitting walls moving to OpenTK / shared projects.
Here is my current issue
