Actually, the most monstrous pig in Visual Studio for me is SSDT (Microsoft&#x27;s SQL-code development environment within VS).  That&#x27;s a bit offtopic since it&#x27;s for SQL development and not C#, and they made a little bit of improvement in 2015, but still: it&#x27;s a pathetic monster.<p>In general, anything that tries to pop-open a GUI and just <i>drags</i> makes me roll my eyes.  EDMX files, I&#x27;m looking in your direction.
