Yeah I don't think I could do .NET development anymore without ReSharper. Makes me wonder how much time I wasted by using Eclipse in my Java days instead of just forking over the cash for IDEA.
I have to disagree with both of these guys, it was so slow in Visual Studio 2013 that I actually disabled it. Then I was forced to re-enable it when I couldn't live without the functionality.
The sentence about Eclipse was merely a side note and not related to the question about ReSharper. Sorry if that was not clear enough. :) I know that ReSharper does a lot of magic that is lacking in Eclipse, unfortunately.
