I\'ve installed Visual Studio 2015, but the ssdt features are missing as you can see below
I checked the ssdt option at the setup, and the only thing i did
Link provided allows downloading SSDT_14.0.50730.0
It did not help me.
This link https://msdn.microsoft.com/he-il/mt429383 You can download SSDT_14.0.51215.0 SQL Server Data Tools in Visual Studio Preview 2015
That solved the problem.
