This sample shows how to use MSBuild (available with Visual Studio 2005) to build, deploy, and undeploy a BizTalk 2006 Solution. This sample does not use an MSI or a binding file and build, binds, and deploys all BizTalk and .Net code using MSBuild Tasks. This sample uses the custom tasks developed by Microsoft UK and available on GotDotNet.
This sample will work with BizTalk 2006 and BizTalk 2006 R2.
