I was watching a video on how to do something in video studio and saw the presenter left clicked on an item it he was given the option to resolve the dll. For example, suppose you write..
StopWatch sw = new StopWatch();
The code won't compile because you don't have the correct using statement above. So he left clicked on "StopWatch" the option came up "Resolve Dll" and he clicked on that and
using System.Diagnostics;
appeared at the top of the page. I assume this is some kind of visual studio extension. I don't know what it is though. Could you tell me where I can get this?
