Can someone give me a list of states preserved by PreserveOpenGLStates()?
I tried looking this up in the C# documentation, but it wasn't mentioned.
I really want to use SFML for rendering, because I can't figure out how to render the way I need to using XNA, but SFML seems to be doing some weird coordinate system changes that prevents OpenGL rendering from working the way it does in C and C++ (animations are fucked up, and when rendering triangles all seem to be rendered in the same place).
I tried editing the Nehe example in the Tao distribution to ensure that this was in fact a problem with SFML, but the Tao examples all keep crashing my computer (even when I compile as 32bit, as I'm on a 64bit system).

I also tried disabling the states by calling App.PreserveOpenGLStates(false), but that made me unable to render anything at all (except the SFML image).

Just out of curiosity why do you want to use SFML with XNA? I see no point in attempting to use both. It would be too painful with no benefit.

I'm not trying to use SFML with XNA, I'm trying to use SFML and OpenGL instead of XNA!!
I thought it would be easy but SFML is giving me a really hard time. I need to know specifically which states are preserved when calling RenderWindow.PreserveOpenGLStates()

Why don't you simply look at the source code? Honestly, I don't remmeber what this function did in SFML 1.6.
