This MOC style lab is the second one of the series of labs that I'll write about how to develop the BizTalk adapters. Especially, this one will show you how to develop BizTalk In Process File Receive Adapter in C#. The purpose of this lab isn’t to provide every details and best practices of the development of the BizTalk adapter. This adapter sample code doesn’t use any abstraction layer such as Base Adapter. After completing this lab, I think that you can understand the big picture and you can continue to develop more sophisticated your own adapters.
