A problem with VSTS source control if you are working with a web site not on port 80
If you are working with a website that is under control and is not working with port 80, you will see problems if you are trying to get it on another machine.
It seems that currently beta 2 doesn't care about custom ports even if they are inside the solution file. as a workaround always work on the default port 80 and everything will work fine.
