Hello SharePoint Developers! We just went live with an updated download for the SharePoint 2010 Software Development Kit (SDK) ! The MAY2010 version of the SDK aligns with the “RTM” versions of SharePoint Server 2010 and SharePoint Foundation 2010, so you will get the latest information about extending, customizing, and writing code for SharePoint 2010.
