VSTS | TFS 2018 | TFS 2017
This topic covers deleting a Git branch via the web in VSTS and TFS. If you need to delete a Git branch in your own repo from Visual Studio or the command line, follow these steps in the VSTS Git tutorial.
Open your repo on the web and select the Branches view.
Locate your branch on the branches page. If you don't see it, select All to view all branches and filter the branches using the Search all branches box in the upper right.
Select the trashcan icon next to the branch you want to delete.
