I am attempting to switch to the TFS 2015 SDK dlls (Version 14) for a few reasons. First, they are in nuget and second, the 2013 SDK dlls (Version 12) require the 32-bit flag flipped in IIS.

I pulled down nutget package and the namespaces all line up with the existing version 12 namespaces.

Everything compiles fine and there was no error on local deployment.

However, when I attempt to load projects using the WorkItemStore service.

TfsTeamProjectCollection collection = new TfsTeamProjectCollection(URL);
var service = collection.GetService<WorkItemStore>();

I get:

Additional information: Unable to load DLL 'Microsoft.WITDataStore64.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

When I switch back on the 32 bt flag in IIS I get:

Additional information: Unable to load DLL 'Microsoft.WITDataStore32.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Note: this was all working code, all I did was remove the references to the GAC assemblies and add the NUGET package.

According to Microsoft, the nuget package should work with TFS 2013 and work for users for the 2013 SDK

Existing Windows apps leveraging an older version of the TFS Client OM.

None of the above worked for me. I had to copy that file to my C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE folder (found this out by using procmon to see where my app was looking for it).
