Here are the first few paragraphs from the paper giving a brief introduction of it's content.
With the realization of the benefits of developing and orchestrating unified business solutions, today’s business organizations adopt the paradigm of Service Oriented Architecture (SOA)-based solution development for the execution of dynamically composed business processes. However, due to the disparate nature of the diverse business applications that exist in an enterprise, many organizations experience daunting challenges in integrating these business applications and services.
This paper discusses the use of Microsoft® BizTalk® Server 2006 R2 and its WCF adapters as a platform for service orientation that alleviates the aforementioned integration challenges. The paper emphasizes the configuration and integration of custom WCF bindings with BizTalk solutions, through the use of the above adapter platform. Furthermore, the paper provides concrete solutions for the identified integration concerns that apply to the orchestration of services through the use of custom WCF bindings.
