I decided to share all my interesting reads and resources month by month with my blog readers. You can find these posts by searching on the label Links. I'll try to order the resources in logical categories. If you would like to see some interesting stuff added in the next month, don't hesitate to post a comment.
So this is my Links post for April 2009.

SharePoint – Development and Programming
