This error led to a big delay in my work.
This happened when I updated my nuget packages, especially Windows Azure Storage.
Then, when I start the cloud project, it gives me this error:
Server Error in '/' Application.
There is a type mismatch between the client and the service. Type '[ProjectNamespace].Merchants.DeviceRegistration' is not an entity type, but the type in the response payload represents an entity type.

I absolutely do not understand how to find a solution for this.
Edit
Here is a later version:
I also notice that a later version generates this request:

Edit 2
To add more information, I also did the following:
- Uninstall all nuget packages and restore them one by one.
- The updated nuget.exe file, as well as all nuget packages, I even updated Windows Azure Tools for Visual Studio 2012. Version 2.2 version
