I'm not familiar with Telerik Test Studio, so don't understand the requirement for absolute paths - do you mean when specifying the endpoints in a ClientConfig?
Anyway, our Windows authentication documentation is somewhat scattered. but here are some places to start:
- You only need the EntityService.svc and EntityServer.svc files if you have not registered a virtual path provider in the application_start logic in global.asax. The global.asax files provided with DevForce samples and templates all register the provider.
- You can override ServiceHostEvents and/or make web.confg changes to modify the binding to accept Windows credentials.
- You can override ServiceProxyEvents and/or use a ServiceReferences.ClientConfig file, though no changes are required on the Silverlight client to use Windows authentication.
