C# support in IntelliJ would be a dream come true!

(yes, I know about ReSharper - but that's just lipstick on a pig)

Pig? VS is considered one of the best IDEs out there. On par, if not better than IntelliJ.

If it was better, it would not need ReSharper.

I use both on a daily basis, and VS + Resharper beats the crap out of IntelliJ, IMO. My opinion might be different if I had to pay for my licenses, but independent of cost, VS wins.
