I've been trying to document everything i can think of before my departure from Rapidparts. This means i've been spending most of my time using Word and PowerPoint rather than my usual development tools.
I have assembled a helpful set of applications to assist with programming that i will miss once i leave the Windows world behind. At home, it will be just me and my Mac. Of course i'll miss Visual Studio 2005, which makes it so easy to program in C# and the other .NET languages. My next favorite tool would be Fiddler. It's perfect for viewing raw HTTP traffic and think all web developers should have it installed. It's helpful for diagnosing problems involving redirects, correctly streaming files to the client, and watching how other web applications work. The folks at Sysinternals also provide many useful tools for free. My two favorites are FileMon and Process Explorer, both of which have helped to solve pesky "Access Denied" errors and other permissions problems. And i can't forget .Net Reflector which is great for peeking inside the Microsoft .NET classes to see exactly how they work.
