SharePoint 2010 versus SharePoint 2007 Object Model (Microsoft.SharePoint.dll)

There are the differences between the new object model (Microsoft.SharePoint.dll) and the old.  Some classes/interfaces/enums were removed, but nothing that looks to hurt anyone.  The really cool part though...no properties or methods were removed between the two versions (doesn't mean that they are not depreciated however)!  NOTE:This is based on a beta version of SharePoint 2010.

• Classes/Interfaces/Enums in 2007:   3225
• Classes/Interfaces/Enums in 2010:   6658
• New namespaces in 2010:    46
