    Hi John,

    This is the same problem we used to have with the Facebook and Twitter DLL's.  Telerik did not add the Microsot Azure DLL's as references to the SitefinityWebApp project.  Because of this, they have the annoying capacity of disappearing.  This happens most often to me when the Web application in development under Visual Studio and do a REBUILD.

    To fix the problem, add the following DLL's as references to the SitefinityWebApp project, and make sure "Copy Local" is set to true...

    Microsoft.WindowsAzure.Diagnostics
    Microsoft.WindowsAzure.ServiceRuntime
    Microsoft.WindowsAzure.StorageClient

    You'll probably have to go to your Sitefinity Installations _EmptyProject\Bin folder to get the dll's and put them back into your sites BIN folder.

    I have attached a screenshot of DLL's referenced in the SitefinityWebApp Project from Visual Studio...

    We managed to resolve this by copying all the DLLs from the bin of a local development version (successful upgrade) to the bin of the broken project on the production server. Next we added all the DLLs as references and re-built the solution.
