Back in February, Paul Andrew (Technical Product Manager of WF) has announced that this march we will have the first CTP of BPEL (Business Process Execution Language) activities for WF. Earlier today, March CTP of BPEL Activities became available for download.
From the download page:
"BPEL for Windows Workflow Foundation (WF) is an add on for Windows Workflow Foundation in the .NET Framework 3.0. BPEL is the Business Process Execution Language and this download is an unsupported Community Technology Preview (CTP) for using this technology with WF. The download, which is aimed at software developers, provides import and export tools for BPEL and includes WF activities representing BPEL for the WF designer in Visual Studio 2005.
Developers using Visual Studio 2005 can benefit from the WF designer for the modification of BPEL workflows."
