I've set up a web service that uses ESRI's REST API spec. This allows me to make requests using the (Silverlight)/WPF SDK. If I turn on windows authentication though, I get a 401 error when using GeoProcessor.ExecuteAsynch.
I can successfully call the same url with a WebClient with credentials set:
WebClient c = new WebClient(); c.Credentials = CredentialCache.DefaultCredentials;
If I use WebClient, then I have to deserialize ESRI's json, which is non-trivial, so I'd really like to use Geoprocessor.ExecuteAsynch instead.
Is there some way to send credentials with Geoprocessor?
