This application is an end-to-end sample application for .NET Enterprise Application Server technologies. It is a service-oriented application based on .Net 3.5 utilizing Windows Communication Foundation (WCF) and ASP.NET, and illustrates many of the .NET 3.5 enterprise development technologies that can be used for building "enterprise-connected" applications.

The application also offers a rich set of interoperability options with non-Microsoft platforms. This includes interoperability with Java-based application servers and IBM WebSphere's Trade 6.1 sample application, and open-source based front-ends and services from WSO2 and other vendors. The .NET services also include a data access layer for both Microsoft SQL Server and Oracle 11G databases. The application offers an excellent opportunity for developers to learn about .NET and building interoperable, service-oriented applications.
