Setting up Xamarin Studio Version Control with TFS + git

I am going to list all steps I took to be as complete as possible.

1. First of all, I created a hosted TFS account and added a New Team Project + Git
2. I then had to create alternative login credentials since you cannot have an @ symbol in your login info. To set up alternate creds in Visual Studio Team Services (VSTS), click on your name on the top right -> My Profile -> Credentials
3. After enabling the alternative credentials open Xamarin Studio. In my case I had a solution that I wanted to add so I had my solution file open as well.
4. Under the Version Control menu item select Publish (Only available with solution file open)
5. Select the Registered Repositiories tab and select Add
6. Enter an appropriate name. Select https protocol.
7. Enter your hosted TFS URL ie. xxx.visualstudio.com.
8. For port, enter 443.
9. The path will be: /DefaultCollection/_git/ + project name (exactly as you typed it including spaces)
10. User will be the alternative username you created in step 2. Click OK on both open windows.
11. You will be prompted to confirm publishing. Select OK.
12. You will then be prompted for your password. Enter you alternative password you created in step 2. If you accidentally enter the wrong password here, you must delete the entry from your key chain. Instructions can be found here

Your TFS + git integration with Xamarin Studio should be complete! If you have any other issues I will try my best to help with them.

In step 12. on Windows 8 and you entered the wrong password you will have to fix it in Credential Manager.

In windows 8

In Control Panel,Open Credential Manager,On the top of the page you have two options, select "Windows Credentials".Under "Generic Credentials" look for a record for "your.visualstudio.com" click to expand and select remove.Now if you publish from Xamarin Studio you will be prompted for your password again.

I had problems connecting to my visualstudio.com repository even when following these instructions. What I did was to use XCode to checkout (or clone) the repository. I then opened my solution in Xamarin and it picked up the repository info just fine.
