3D Graphics in C#

I spent some time this morning looking at options for drawing 3D graphics from C# code.

I've used OpenGL in the past, so I started by looking for C# libraries to do OpenGL. I didn't see a lot, and came across this post:

You can use DirectX for 3D.

Looking for OpenGL support in .NET is like looking for DirectX support on a Mac.

That made me think I was barking up the wrong tree, so I started looking for some DirectX samples, and came across the Free C# DirectX Control by Jeremy Spiller and a Direct3D Control by Ryan Cook, both of which I'll take a peek at. There is also XNA from Microsoft, but it is not clear to me how much that is applicable to non-games.

And, of course, I could always do the transforms and drawing myself using System.Drawing, but that doesn't seem like a good use of my time.
