I've had a large number of emails from .NET developers who want more information about SharePoint Development.  I decided to create this static page on my blog as a FAQ.  I'll section it so that it's more usable.

Getting Started

My 12-part MSDN webcast series (with Mike Benkovich) on SharePoint for Developers - put 'lynn langit' -OR- 'mike benkovich' in the 'all of these words' keywords search section
(you will also get some of my geekSpeak shows and some of Mike's newer SharePoint webcasts as well)
