There is a type mismatch between the client and the service. An error after updating azure storage

Question

This error brought a lot of delay to my work.
This happened when I upgraded my nuget packages, especially the Windows Azure Storage.

Then when I run 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. Please ensure that types defined on the client match the data model of the service, or update the service reference on the client.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.18446  

Here is the query being generated:

{https://[accountname].table.core.windows.net/MerchantApplication()?$filter=PartitionKey eq '635180925195321704_38913b36f10d47e4916671ba51e2184c' and RowKey eq 'D_f974c1da570946f183f4f4640534a343'}
    base {System.Data.Services.Client.DataServiceQuery<[ProjectNamespace].Merchants.DeviceRegistration>}: {https://[accountname].table.core.windows.net/MerchantApplication()?$filter=PartitionKey eq '635180925195321704_38913b36f10d47e4916671ba51e2184c' and RowKey eq 'D_f974c1da570946f183f4f4640534a343'}  

I am totally out of idea on finding solution for this.

Edit

Here is the later version:

I also notice that the later version generates this query:

{https://[accountname].table.core.windows.net/MerchantApplication()?$filter=(PartitionKey eq '635180925195321704_38913b36f10d47e4916671ba51e2184c') and (RowKey eq 'D_f974c1da570946f183f4f4640534a343')}
    base {System.Data.Services.Client.DataServiceQuery<[ProjectNameSpace].Merchants.DeviceRegistration>}: {https://[accountname].table.core.windows.net/MerchantApplication()?$filter=(PartitionKey eq '635180925195321704_38913b36f10d47e4916671ba51e2184c') and (RowKey eq 'D_f974c1da570946f183f4f4640534a343')}

Edit 2

To add more information, I also did the following:

• Remove all nuget packages and restore them one by one
• Updated nuget.exe as well as all nuget packages, I even updated Windows Azure Tools for Visual Studio 2012. The version is 2.2
• I have tried all the possible solutions I found on the net related to this question.

But in the end, the problem above was not solved.
For now, I go back to the previous project files. But this project is having problem when deploying to production server (Windows Azure), but not in staging server. It is really weird.

Answer 1

See here for the answer that worked for me.

Basically, add a DataServiceKey attribute to your TableEntity derived class (Merchants.DeviceRegistration?) that includes the PartitionKey and RowKey properties.

I imagine your class declaration will need to look something like the following:

[DataServiceKey("PartitionKey", "RowKey")]
DeviceRegistration : TableEntity
