DevPartner Profiler Community Edition
Went to an MSDN Event (Turbo Charging ASP.NET Applications) last night in Ottawa. Although I didn't bite on any of Compuware's pitches for various products, I was very impressed with there profiler (DevPartner Profiler Community Edition) for VS.NET that was used throughout the presentation. Integrates very nicely with the VS.NET IDE, quality/content & presentation of profiling is well done, nice graphing capability, and the documentation seemed sufficient and complete.
Ironic that none of the products they pitched impressed me, however this FREE profiler that they were using had me itching to get out of my seat so I could run home and give it a test drive myself. Go figure!
