All service calls from silverlight failing

I have a strange issue. All the webservice calls from silverlight application in my computer are failing. When I checked with fiddler, I can see that all the services are properly returning data. But the service calls in silverlight end up in the Communication Exception. The remote server returned an error: Not found.

I am using silverlight 4.0.开发者_Python百科

Any help would be appreciated.

are you calling remote or local services? If you are calling remote services, it could be there is no cross-domain policy in place on the remote server. try making a "normal" asp.net page or console app (etc.) that calls the service. If that is successfull, then this is probably the issue. you would have to make a sort of "proxy" webservice locally that calls the remote one--unless it is your own webservice and you can place a clientaccesspolicy.xml in there. here is a really good article on the subject.

The issue was really small. The disk space in C: drive of my machine was very low. Once some space got freed up, the issue got resolved. Thanks to all who helped.
