I am automating a TFS branching process with DotNet core 2.2. We are using TFS 2018.

How can I create a new branch in TFS source control using C#?

I have been able to queue a build a do some other operations.

`Microsoft.TeamFoundation.VersionControl.Client.VersionControlServer` has a method for `CreateBranch` but I have not been able to instantiate a `VersionControlServer`. Old documentation shows this is done with `TfsTeamProjectCollection` but I can't find any libraries with that class.

A lot of the MSDN documentation goes to obsolete or deprecated references.

***UPDATE***
I have found that TfsTeamProjectCollection is in MicrosoftTeamFoundationServer.ExtendedClient if I install version 14.83.0, but the current version is 16.143.2.  

When I drop back to this old version I get runtime errors associated with versions of other packages. If I downgrade them there are several build errors so I will need to refactor. I can't downgrade, and shouldn't have to.

What has replaced this?
