I'm trying to make a opengl wrapper for winforms(.net). Basically you code in gdi+ syntax but it gets rendered for opengl(using glcontrol of opentk).

Which mode should I use for rendering ui? It has to be fast enough to support lagless animations and image-drawing. ImmediateDirect mode (glBegin, glEnd) is easy but I've read there are performance issues. On the other hand, retained mode will be relatively much complex to implement.

My preference is first make for immediate mode then move to retained as I progress. Are there any issues with immediate mode(like missing functionality

Should I use retained mode or immediate mode
