Walkthrough: Displaying Statement Completion" does not work on Visual studio 2015

I tried following walk-through on Visual Studio 2015 but it didn't work. https://msdn.microsoft.com/en-us/library/ee372314.aspx

The debug point on TestCompletionCommandHandler.Exec() is not hitting. So I hope something not work from the beginning. Anyway this is working on Visual Studio 2013.

I just followed the whole walk-through on msdn.microsoft.com/en-us/library/ee372314.aspx . And then auto completion not working as explained on walk-through. So this walk-through is simply doesn't work on visual studio 2015.
