Jon Flanders has posted an excellent template wizard for implementing enterprise integration patters in BizTalk Server. Once installed, it will put a folder called Pattern Templates under your BizTalk Projects folder in Visual Studios.
This wizard will walk you through the creation of the patterns step-by-step. It creates correlations sets, messages, and orchestrations for you.
It covers Asynchronous Aggregation, First-In First-Out (three different types), Interrupter, and Retry.
Get more information and download the wizard from Jon’s blog.
