Using the Free CLR Profiler with the ASP.NET 2.0 WebDev Web-Server (aka Cassini)
K. Scott Allen has made some great blog posts the last few months. Yesterday he posted a new blog entry on how to use the free Microsoft CLR Profiler that is now available for download to analyze ASP.NET 2.0 applications running in the built-in VS web-server (aka Cassini).
If you aren't using a profiler yet to tune your code, you should really set aside some time to come up to speed with how they work and what they can do for you. They can really make a word of difference with your performance if used correctly.
Hope this helps,
Scott
