Pull is just like fetch, but it merges the changes automatically after downloading them. If there exist any merge conflicts, though Git takes care most of them, it will ask you to resolve them first before continuing.

To apply the remote changes to your local, open Team Explorer and navigate to Sync view. Then you can click either Sync or Pull to download the changes and merge them:

The merge operation will keep the commit history of your local changes intact, so that when you share your branch with the push command, Git will understand how others should merge your changes.
