Unable to load DLL ‘Microsoft.WITDataStore32.dll’ (TeamFoundation.WorkItemTracking)

You don’t need to install the TFS object model/Team Explorer anymore. You can use the NuGet package

Also with the NuGet package, you may run into the same issue that your application cannot find the native DLL.

Microsoft.WITDataStore*.dll is part of the ExtendedClient package, they are native dlls and cannot be referenced in managed project.
You will need to manually copy the dll into your bin folder for runtime resolution.

Microsoft.WITDataStore32.dll is in ..\Microsoft.TeamFoundationServer.ExtendedClient.14.83.1\lib\native\x86
Microsoft.WITDataStore64.dll is in ..\Microsoft.TeamFoundationServer.ExtendedClient.14.83.1\lib\native\amd64

(note these paths point to the NuGet package folder)
