.NET Polygon triangulation library

Hey, I'm looking for a library that will triangulate planar polygons with openings.

I've seen a couple other questions that ask about triangulation (see Polygon Triangulation with Holes and Polygon triangulation), but I'm looking for something that I can use开发者_高级运维 from .NET without having to write a managed wrapper.

Anyone know of a good .NET geometry calculation library? Or is there some way I can do this in DirectX without getting up to my elbows in unmanaged API calls?

XNA Framework maybe?

Or you can search in CodeProject and find some small libs like this one
