I have been useing the .net 4.0 sandbox site to test a Silverlight app and it has been working fine. It uses WCF Ria Services and I could connect with no problem. Now that .net 4.0 has been released, I upgraded my web hosting to the 4 framework and uploaded the same files but there is a problem with the Ria Services. It gives me the message: Load operation failed for query. The remote server returned an error: Not Found. Like I said, I can upload this same site to the sandbox and it works fine. I have ensured the required Ria DLL's have been uploaded as per the post. Greg
The most likely problem is authentication problem. Did you make sure you turn off Basic Authentication and just use anonymous.
Fiddler tells me this: IIS specified authentication schemes 'Basic, Anonymous', but the binding only supports specification of exactly one authentication scheme. So, how do I turn off the basic authentication in the control panel? Greg
