Many large enterprises have disparate systems including legacy mainframe, databases, packaged and homegrown applications that need to be integrated with each other to provide end user solutions. The technology integration becomes more complex after companies go through Mergers and Acquisitions, which are more prevalent in case of Financial and Telecom Industry verticals. Back-end systems such as SAP, PeopleSoft, Siebel, Oracle, IBM CICS, IMS, VSAM and Relational Databases are collectively known as Line-of-Business (LOB) applications. The line-of-business adapters provide legacy modernization by bridging existing back-end applications with the modern interfaces. Windows Communication Foundation (WCF) provides a unified framework for building distributed applications, including creating adapters to existing applications.

The WCF LOB Adapter SDK provides for a simplified programming model on top of WCF Channel Model to enable adapter developers in creating service-oriented interfaces to existing systems and applications. The Adapter SDK surfaces a target system adapter as a WCF Binding. The goal of the WCF LOB Adapter SDK is to facilitate uniform development of reusable metadata-oriented WCF-based adapters that enable enterprise applications, databases and messaging platforms to integrate with each other. The same adapter binding developed using Adapter SDK can be reused in multiple .NET applications including Custom .NET Applications, BizTalk Server 2006 R2, Microsoft Office SharePoint Server 2007 and Microsoft SQL Server Integration Services. In addition, Adapter SDK provides a common metadata object model to expose target system metadata, for adapter consumers to browse, search and retrieve WCF contracts from the adapter.
