The Microsoft patterns and practices team has just released a Guidance Explorer. This is an easy way to find and lookup all the various how to's, samples and other goodies that come out of p&p.

Best of all though, you can add our own stuff to it (though I'm not quite sure how yet).

There's an online beta (doesn't work in firefox, and it's a bit crappy in IE) and a downloadable copy.

The download is available from gotdotnet, and installation is just a matter of unzipping into a folder and then creating a shortcut to the .exe.
