Set the
<serviceDebug includeExceptionDetailInFaults="false" />
to
<serviceDebug includeExceptionDetailInFaults="true" />
in order to get more details
and try to run the process again
Solution 2
I reconfigured my project recently and ran into this error.
It was a setup error, my service DLLs weren't being placed in the right directory when publishing the website.

Im trying to create my first WCF restful service. In VS2010 I open weddingservice.svc and then hit F5. A browser opens to http://localhost:50043/weddingservice.svc But there, this is the error I get:

Below my code, I hope anyone is able to see what Im doing wrong. Am I not using the correct URI? What did I miss?
weddingservice.svc

Adam about 12 yearsThat helped! I had to add a namespace BEFORE the RestService namespace! It now works! Great! Thanks!
