We are happy to announce that we have released the WF ADO.NET Activity Pack CTP1 on CodePlex.
The WF ADO.NET Activity Pack CTP1 contains a set of WF 4 Activities based on .NET Framework Data Providers. These activities enable accessing a database through SQL commands or stored procedures within a workflow. You can drag-and-drop the ADO.NET Activities to your designer surface and access the database just like what you can do with ADO.NET. It is a very simple way for you to integrate business data into your workflows.
