Project Mole or visual studio visualizers on steroids
Visual Studio visualizers are pretty cool and can help you quite a bit when debugging but you need to develop them and that just ads to the workload. So how about having someone else do it? Well Microsoft added a few visualizers to VS2008 and VS2008 but they are pretty much limited to text, html and XML data.
Luckily some people liked the idea of using visualizers and actually decided to take it to the next level with project Mole.
Its a really great viewer to inspect your data and the "Black Ops" feature that allows you to inspect all private members is awesome.
One quick tip: If you want to use the Mole with any variable use the "new WeakReference(variable)" in the watch window trick!
