azure error :Could not load file or assembly 'Microsoft.TeamFoundation.WorkItemTracking.Client.DataStoreLoader' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Question

I am getting this error when I try to run my web application on local machine appfabric  as well as in azure cloud .

Any comments on why this is happening and any soultions to resolve this error .?

I can also see a warning message "

my project abc contains the following assembly: C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.TeamFoundation.WorkItemTracking.Client.DataStoreLoader.dll. This assembly is not compatible with the 64-bit processor architecture used by IIS on Windows Azure. To make sure that the role starts, you must replace this assembly with one that is compatible with this architecture. "

If this is the cause,then where can I get the same dll that is compatible ?

Given below is the actual error message I am getting

Server Error in '/' Application.
