How to push unsynced commits to GitHub?
github
Solution
It looks like you do not have the upstream remote / branch configured for this branch. Visual Studio operates as if the "push.default" configuration is set to "upstream".
If you go to the branches page, this branch should be listed under the "Unpublished" branches section. From that page, you can choose to "publish" this branch by right clicking on the unpublished branch and selecting publish in the resulting context menu. This will push the branch to the origin remote (with a branch of the same name as your local branch) and set the upstream tracking information for this branch. From then on, you can push and fetch from the Unsynced Commits page.
Here is a screen capture of where you need to go to publish an unpublished branch:
Problem
I have a GitHub source control tool added to my copy of Visual Studio 2013 and when I right click on the solution and make a commit it says created the commit locally. When I try to sync the commit with the server, the sync button is greyed out. My question is how do I set it up or what steps do I take so that the commit is pushed to the server?
