SharePoint 2010 Developer Center
Over the coming months I imagine there will be many posts about SharePoint 2010. Only this week there was a conference in Las Vegas for developers to get their hands dirty with it.
From a developers point of view, if you didn’t make it (like me) then the Micorosoft SharePoint 2010 Developer Center is worth a look.
There is a great introductory video here. I’ve always been a fan of MSDN, yes occasionally there are ommisions, but for the most part it is a tremendous resource.
