Simple WCF service with REST - Resource cannot be found - error with ASP.NET Debug Server?

I'm testing a very simple WCF-Service with REST functionality enabl开发者_开发问答ed. It works fine on IIS, but the VS2010 debug webserver always says "The resource cannot be found" when appending the parameter after the .svc file in the browser uri. Is this a known issue with the asp.net debug webserver that it cannot work with REST or am I doing anything wrong? (again: with IIS, it works)
