Introduction
The .NET StockTrader is an end-to-end sample application based on an online stock-trading
scenario. The application is a new Microsoft .NET sample application designed to illustrate the use
of the Windows Communication Foundation (WCF) technologies in an end-to-end service-oriented
architecture. As such, the application illustrates many best-practice programming practices for
.NET and WCF including the use of an n-tier, service-oriented design. As a benchmark sample and
downloadable benchmark kit, the application also illustrates best-practice programming for
building high-performance and scalable service-oriented applications using Microsoft .NET and
WCF.

.NET StockTrader and Standards-based Interoperability with non-Microsoft
Platforms
The application is functionally equivalent to the IBM WebSphere Trade 6.1 sample benchmark
application, and serves to illustrate interoperability between .NET, commercial Java EE application
servers such as IBM WebSphere; and open-source platforms including those based on Java and PHP. All
of these platforms today support both basic Web Services and Advanced Web Services based on the WS-
* standards. In .NET StockTrader 2.0, all of the services in the application are exposed, via WCF, as
industry-standard Web Services. The .NET StockTrader Web application seamlessly interoperates with
the backend Java services of the WebSphere Trade 6.1 application. Conversely, the WebSphere Trade
6.1 Web application is able to seamlessly utilize the backend services of the .NET StockTrader. In each
case, a simple endpoint configuration allows this interoperability, with no code changes required to
either application.
Furthermore, WSO2 (
http://wso2.org/interop/stocktrader
) has developed both a front end (in PHP) and
middle tier services (both in open-source Java and in open-source PHP) that fully integrate with the .NET
StockTrader, for plug and play with both services and front-ends over the WS-* standards. This
interoperability includes illustrating WS-Security for
