To start off, let's create a standard class library project. This class library can be .net 4.5 as you need to create a library that is equal to or higher than the reference you add to it, for which our main reference will be Microsoft.TeamFoundation.WorkItemTracking.Client.dll in our case. This is currently at .net 4.5:

As you can notice, we'll place this class library in the source control as well. Next, we'll add some references. The first of the references will be to Microsoft.TeamFoundation.WorkItemTracking.Client.dll and Microsoft.TeamFoundation.WorkItemTracking.Controls.dll.

If, for some reason, you don't find one of these references, navigate to %ProgramFiles(x86)%\Microsoft Visual Studio 14.0\Common7\IDE in Windows Explorer and search for the assembly. In my case, I had to do this for my assembly references. Make sure you have version 14.0 of both assemblies added as it won't work if you have something else, such as 12, and you...
