Resharper 5.0 - initial impressions

Question

Now that VS 2010 is officially released, I'm thinking of upgrading to Resharper 5.0 and I just wondered if any of you could provide any feedback on your impressions so far.

Some specific questions:

1. I like Resharper a lot, but it's pretty slow if you have a slow disk (one of my machines has a 5400RPM drive and it does not run very optimally on that machine.). I just wondered if you had noticed any speed improvements in 5.0.
2. Is Resharper 5.0 required for VS 2010, or will Resharper 4.5.1 still work? I couldn't find anything definitive on the JetBrains website, but I may have just missed it. The impression I get is 5.0 is required for VS 2010.
3. Any other feedback you have on Resharper 5.0 and what you like/dislike about it is much appreciated. I'm not sure when I'm going to be officially moving to VS 2010, but I guess I could go ahead and get Resharper 5.0 even if I stay on VS 2008 for a while. Are there any new features in 5.0 that you've found that are really nice which aren't in the 4.5.1 version (I checked out the features page, but nothing really jumps out except for the native nunit support which looks nice).?

Thanks for your feedback.

Answer 1

Browsing .Net Framework source code with just a single F12 click is quite impressive.

Answer 2

First off all Resharper 5.0 supports VS 2010. The older versions won't support VS 2010. Since I have been using Resharper 5.0 for a few days I can say that it is as good as the older version. For enhancements you can check this page : http://www.jetbrains.com/resharper/whatsnew/index.html?R5blog

Answer 3

R# 5.0 RTM is horribly slow with VS2010 RTM. I've actually just disabled it.

I'm having all sorts of UI lag issues. I have a Win7 X64 box, quad core 2.4GHz with 8Gb and Quadro graphics card and SSD disks and it's still almost unusable.

Answer 4

Performance has been comparable with Resharper 4.5. There are a couple of very nice new features - Inspect > Code Issues in Solution in particular is great. See http://www.jetbrains.com/resharper/whatsnew/index.html?R5blog as mentioned by Semih.
