Here are a few links for developers working with Windows SharePoint Services v3 or Microsoft Office SharePoint Server 2007 Beta 2 Technical Refresh:

• Windows SharePoint Services v3 SDK (CHM file… updated for B2TR)
• Office SharePoint Server 2007 SDK (CHM file… updated for B2TR)
• Visual Studio 2005 Extensions for Windows Workflow Extensions RC5 (compatible with .NET 3.0 RC1)
• Visual Studio 2005 SDK September 2006 refresh

For you WCM folks, the MOSS 2007 B2TR refreshed SDK contains a TON of additions pertaining to WCM. I updated my WCM linkfest page with these updates.
