Process specific Performance Counters in .NET work directly only with Process Names, not Process Ids which can be problematic if you need to monitor performance of multiple instances of the same process. In this post I describe how you can capture multiple processes uniquely and monitor each individually.

.NET is a bit short when it comes to tools that can manipulate UrlEncoded data. If you need to read, create or modify raw querystrings or form data outside of ASP.NET's System.Web context there isn't a clean way to do this and even there if you want to modify url encoded data you'll need to write some code. This article describes a UrlEncodingParser class that lets you read in raw query strings, form data or entire URLs, then lets read, add and update values and then write the values back out. Makes you wonder why that functionality doesn't exist natively somewhere in .NET, eh? Code and samples are provided.
