How can I create a shelveset with VS2017 (using VSTS and git)?
Within the Team Explorer in VS2017, there is no button for shelveset available, just for commit.
Do I have to activate it? Or isn't it available for the current VSTS?
It seems that you're searching for the tools about TFVC (Team Foundation Version Control). Git is a completely different source control system and the tools provided by Visual Studio are different, too.
