Calling all SharePoint enthusiasts…Microsoft released an updated version of the Microsoft Office SharePoint Server 2007 (MOSS 2007) and Windows SharePoint Services 3.0 (WSS v3) SDKs. This is exciting because many features in SharePoint '07 are easy to program against, but hard to determine because of a lack of sufficient documentation. I know this from experience with the many SharePoint '07 projects I had. In addition, Microsoft released a Business Data Catalog editor two days ago. Who knows, it may be better than the BDC Meta-Man. Below is the link to download the BDC editor.
