All TFS clients

The TFS API continues to be sorely underdocumented. This time, let's talk about the .NET one for a change. You're supposed to first construct a VssConnection, then get a client class or several. There's a separate client for source control, a client for work items, one for build/release tasks, etc. Here are all client classes that I could find in TFS 2018u1:
