Poll : Do you hate .NET?
I ask you for no particular reason. You don't even have to give a reason or try to prove your point. It's just about how .NET makes you feel.
My biggest beef (among the parts I've worked with) would be ASP.NET Web Forms, which is an attempt to make web programming just like desktop programming. But if you come from a web programming background its extraordinarily frustrating to have to work around all of the not-quite-right automagic behavior.
On the other hand, despite its occasionally clunky look and feel, Visual Studio is easily the most productive development environment I've worked in (including emacs/command line, TextMate/command line, and XCode).
