ReSharper dotTrace 3.1 Integration PowerToy
dotTrace is Performance and Memory profiler from JetBrains.
dotTrace and ReSharper are tightly integrated. For example, you can profile separate tests in your code base.
dotTrace 4.0 (currently in beta) have a lot new features (you can read about them at EAP page) and fully compatible with coming release of ReSharper 5.0.
But previous release, dotTrace 3.1, is not compatible with ReSharper 5.0.
ReSharper dotTrace 3.1 Integration PowerToy will allow you reconcile dotTrace 3.1 and ReSharper 5.0 together.
