Something great has happened with the speed R# in build 90. Most noticable is that prior to build 90, attaching the managed debugger to a process took ages. Since I installed build 90, attaching the managed debugger to a running process is much faster.
Also, unresponsive periods seem to happen much less often and, when they do arrive, seem to be much shorter than before.
I am attributing this to your hard work. All round, my R#ing experience is much much better with this build.
P.S. I did check and, no, tech support have not doubled my CPU power!
