What library to use for C# to work with OpenGL?

Question

OpenGL

I'm relatively new to C# and I wanted to try graphics with OpenGL, but I realized that I don't know which library to choose for this.

I know about SharpGL, OpenTK, Tao, well, everything seems to be.
Can you suggest which one is better to choose, and are there any others?

I found an article on working with Tao, but the latest version of this library was released already in 2008.
Graphics are not for games, I say right away, but for simple (or not) 2D or 3D images like graphics.

Or would you recommend something else?
