Using rdpsign.exe with c sharp and where to get it

[C# Programming]

Has anyone used rdpsign.exe with c#? Any compatibility issues with .net 3.0 or 3.5?

Any idea where I can download it? Or does anyone have a copy they can attach to the forum (as long as there is no TOS being violated)?

I have the 2008 enterprise iso file, but I do not find it inside of the iso?

Thanks!
