I had the same issue today recently installing VS2015 Community Edition Update 1.
I fixed the problem by just adding the “SQL Server Data Tools” from the VS2015 setup installer… When I ran the installer the first time I selected the “Custom” installation type instead of the “Default”. I wanted to see what install options were available but not select anything different than what was already ticked. My assumption was that whatever was already ticked was essentially the default install. But its not.
