TFS Build: Failed to activate Xamarin license.

While helping a customer setting up a release pipeline for their Xamarin Mobile applications, I noticed that their CI(Continuous Integration) build was failing for some time.

When opening the build results I saw the following error message:

The acquisition of Xamarin by Microsoft made this license check obsolete, so just remove it and  you are good to!
