Problems with REST deployment on IIS7

I can't get my REST serv开发者_Python百科ice to run on IIS7.

It runs fine from VisualStudio 2010 ASP.NET Development Server.

But on IIS i get "HTTP Error 404.0 - Not Found".

I'm guessing it has something to do with the URL routing? How can I verify this?

Happy to give more details about the problem if it can help anyone help me.
