About the BizTalk Orchestration Engine

At run time, the BizTalk Orchestration Engine executes XLANG/s files that are produced by BizTalk Orchestration Designer. Orchestration Designer is a rich graphical tool for visually designing business processes. It generates XLANG/s files that have an .odx extension and contain additional visualization information in their headers and custom attribute information in their bodies.

Note

XLANG/s can be viewed as a messaging language with some of the expression capabilities of C#.

The primary functions of the orchestration engine are:

  • Persistence

  • Hosting the .NET components

  • Transactions

  • Large message support

  • Runtime validation

  • Load throttling
