calling WCF service from asp.net ajax

Hi,

I have found lots of examples of adding an ajax web service method from inside an asp.net application by adding a new ajax enabled web service as a new item to an existing project.  I want to separate all these service methods into a totally separate WCF application.  This would enable me to put the applications on different web servers.

When I try to move the service code to its own WCF application I can't get the service to resolve.

Are there any examples that demonstrate what I am trying to do?

Thanks
