Jesús Rodriguez continues his excellent series of posts on the new features of the .NET 3.0 Adapter Framework (aka WCF adapter framework) included in BizTalk server 2006. This time, he covers some of the facilities available for generating metadata in Line of Business (LOB) adapters like SAP or SQL Server. Worth a look.
On a related note, Jesús also mentioned that his employeer, Two Connect, recently released their new SSIS tasks for SalesForce.com, which complement their existing Salesforce BizTalk Adapter. Cool Stuff.
