Andrew Connell, a SharePoint MVP, hosted two introduction to SharePoint 2010 webinars for developers over the last couple of days in conjuction with DevExpress. These were a really good concise introduction to SharePoint development. I would recommend that anyone who is interested in getting started with SharePoint development take a couple of hours to check these out.

This webinar is also available on the DevExpress Channel.
SharePoint 2010 Data Access

Andrew was also kind enough to publish a wrap-up blog post with links to additional references.
