Microsoft was holding the Professional Developers Conference (PDC) this week. Today, we were informed that at this conference, huge beta invites were given out. Developers were just itching to get a crack at these major new advances on the previous versions. The new Microsoft Silverlight 4, Microsoft Office 2010, and Sharepoint Server 2010 were the special little gifts that Microsoft gave out for the beta testing. Now developers will start sinking their teeth into these juicy new products! Here is the link to the betas.
