Directx mesh from binary file.

posting in the "off-topic" section is much more likely to get you  a good responce, just because more people look at it.  Just to mention.   

Personally, I'd pull my eyes out trying to create a mesh from a binary  file without another tool specifically made to work with meshes.

With C# (do yourself a favor and use VS 2008) you should use SlimDX or XNA if you want to load a mesh from a file. There are like a million of tutorials out there for that.
