Hi,

I am trying to get a .net website to connect to an instance of Dynamics that has recently been upgraded to version 9 (1710 (9.0.2.1470)). I have updated my connection string and installed the latest version of Microsoft.CrmSdk.CoreAssemblies. The solution builds but when i run it locally and it tries to communicate with Dynamics is get an error (see below) I think this is ultimately being caused by the crm returning a 401 error when the site tries to connect to it. i get the same error when i try to use CrmSvcUtil.

Can anyone help me to work out what might be wrong?

Server Error in '/' Application.
