At the SOA & Business Process conference back in October we annouced that Jon Flanders was building an awesome new tool, the BizTalk Server Pattern Wizard. Well, it's done. Actually, Jon posted it on CodePlex quite a while ago, I just forgot to blog about it. My bad.
You should go check this out right away. Not only does the wizard have about a dozen patterns ready to go, but you can turn your own orchestrations into reusable patterns complete with customization parameters and parameter UIs. There is an introductory video here. Most of these patterns come from the BizTalk End To End Scenarios in the docs so you can get more context on their value and inteded use there.
Let us know if you create a cool pattern. We'd love to tell the rest of the community about it!
