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.
Is ReSharper still as slow as it used to be 5 years ago (VS2008)?
Eclipse does a lot of "mind-reading", too.
It is lightning fast on my machine on both VS 2010 and 2012.
I've been using VS2013 with ReSharper 8 (though I've been using RS in general for many years) and the pair seem to be faster than ever.
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.
I'm actually noticing a bit of a regression in Visual Studio 2013/RS 8. My Alt+Enter quick fix menu takes longer to just show up with any suggestions.
Don't get me wrong, Eclipse had a lot of powerful features but never felt as polished as ReSharper does in Visual Studio.
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.
