I use it all the time when developing applications for end users. I don't need the integration but I'm still having issues with the mouse not being recorded when I run an application in debug IIS Express mode. I reported this issue several years ago and it still has not been fixed.
As there is a free community version of Visual Studio that can easily duplicate this issue I see no reason for it not to be fixed. If you have ANYONE there that can build a simple one page asp.net form they can duplicate this issue in less then an hour. I'd be happy to supply it if they know what to do after they received it.
Its frustrating to have to run an application compiled online in a browser window to record the mouse.
