Biztalk Orchestration Question:

XLANG/s can be viewed as a messaging language with some of the expression capabilities of C#. However, code is not portable between XLANG/s and C#. The language is used for orchestrations. XLANG/s statements generally fall into one of two categories: simple statements that act on their own, such as receive or send, and complex statements that contain or group either simple statements or other complex statements, such as scope, parallel, and listen. The semantics embodied in XLANG/s are a reflection of those defined in the Business Process Execution Language for Web Services (BPEL4WS) specification published by Microsoft, IBM, and BEA for the definition of business process semantics.
