Part of me has always been kinda surprised that Microsoft haven't bought ReSharper from JetBrains and integrated it as a special add-in for the Ultimate branch of Visual Studio.<p>Interesting reading nonetheless, the original post has some good comments: <a href="http://blogs.msdn.com/b/mikeormond/archive/2010/09/03/msdn-flash-poll-7-visual-studio-add-ins.aspx" rel="nofollow">http://blogs.msdn.com/b/mikeormond/archive/2010/09/03/msdn-f...</a>
I think that Resharper is too bloated and instable. I use only Metascroll (a continuation of Rockscroll) for a fancy scrollbar and highlighting of intersting stuff in source.
I've been using visual studio quite awhile now, and am still appalled that there is not good integration with any source control system. Subversion is only 3%!? Shouldn't every coder use source control? TFS doesn't count when CVS, SVN, hg, and git are all free and widely spread. VSS doesn't count either =P The subversion plugins are ok at best.<p>ReSharper adds a lot of features to VS that is standard in Eclipse and IntelliJ in the Java world, hence many people love ReSharper, esp transplants from the Java world.
