ReSharper is an awesome plugin I would recommend it to anyone who codes in c# on a regular basis. ReSharper not only helps you code faster it also helps you code better.

How's the performance this time around? Like many others I have installed the previous versions only to uninstall due to sluggish performance.

I agree with Søren on the performance it's pretty much like 3.x but I don't think 3.x was bad either... I'm usually working on medium/big sized code bases and I don't think I've ever considered RS3 to be slow, even with the solution wide error checker turned on.

Of course any plug-in comes with some kind of perf. hit, be it small or big. However, in my experience the perf. you gain as a developer by using RS, vs. the perf. hit you suffer from having it running in the background, is usually a very good trade off.

Brian, I recommend you download the trial and see if you still think the performance is too bad.

Hi

Amen... this product is awesome. I've been installing the latest beta build the past month or so.

My favorite new 4.0 is:

"Clean up code" in the entire solution (both formating, but also some minor "safe" refactorings). This makes it much easier to enforce common coding style.

On a close second comes the new "Errors in solution feature" which finds a lot of small errors in especially ASP.NET solutions.

PS: The performance is great if you ask me... even on big solutions. The startup analyzing takes some time, but after that its great. Of cause the "Background compile" in C# takes some performance, but this feature is such a time saver, that I don't like programing without.

I can only agree with Thomas and the rest of you. I have also used the 4.0 version of ReSharper (though the beta versions until today) on large solutions and I don't think the perf hit is worth mentioning.

One of the things that I've gotten to love a lot is the intellisense ReSharper is able to give me in the ASCX/ASPX pages in ASP.NET solutions.

Thumbs up for ReSharper!
