I am guessing there is no built-in support for TFS (Microsoft Team Foundation Server) version control. I just downloaded and installed the community version of GO. TFS does not appear in the SCM drop down on Add New Pipeline. This is kind of surprising to me, TFS is definitly not the best of breed SCM but it is widely used and seems like an oversight that it is not included by default.
I did a few searches and it looks like the workaround is to use SVNBridge to connect to TFS
is there any good documentation that outlines the needed steps
