I came across Adrian Hamza’s blog today. His blog seems to be totally dedicated to the Sharepoint Adapter for Biztalk.
It looks like it will be a great resource for information on anything related to Sharepoint and Biztalk integration.
The post I like best gives a detailed comparison between the GotDotNet Sharepoint Adapter and the new Biztalk 2006 Sharepoint Adapter.
I think the best new “feature” of the Sharepoint Adapter is that it will be supported by Microsoft. I know this has held up a lot of customers from using it in the past.
