It's been a while since I mentioned this, but on the Right-hand sidebar of WynApse.com is an 'Outlook Bar' of headings such as 'Code Reference', 'Cheat Sheets', 'WP7', etc.
If you click one of the headings, it opens up a list of web links to reference material I've squirreled away.
I recently filled out the WP7 and Lightswitch sections with some links. For instance here is what is in the WP7 section right now:
Feel free to use that bar as a resource, there's lots of good stuff in there, and if you find a broken link let me know.
As you're using it, remember it is a Silverlight 1.0 island of code on the Master Page :)
