Insert an App.config file to the project AzureForDotNetDeveloperWCFServiceLibrary and modify it as shown in Listing 4-4. Listing 4-4.

Add a new Visual Studio Team Test project called HostWCFServiceUnitTest from the Solution Explorer panel. 7. Add a service reference to the client test project HostWCFServiceUnitTest and enter a name for that reference (the name can be changed after adding the reference) as shown in Figure 4-4. Figure 4-4. Add a service reference to the client application HostWCFServiceUnitTest CHAPTER 4 ■ WINDOWS AZURE APPLICATION INTEGRATION USING WCF 121 8. Visual Studio will generate a service client proxy. There is actually a package generated, including service.wsdl, the web service definition language file, and Reference.cs. The first file contains information of the endpoint address, service contract definition, and data object definitions. The second one is where the C# classes have been generated by Visual Studio using the WSDL file. Listing 4-5 is extracted from the generated service.wsdl file, and Listing 4- 6 is the C# client proxy classes generated by Visual Studio. If an application, either a Windows application or a web application, is also developed using the .NET platform, the generated C# proxy classes can be directly referenced. An application built with other platforms, such as Java, can use the generated WSDL to create its own web service proxy and communicate with this service. The auto-generated proxy package should contain all service interface functions as well as the data structure container classes. To use these generated classes from client applications should be straightforward as with other regular C# classes. Listing 4-5. Extract from the Generated WSDL File service.wsdl <wsdl:service name="UserRegisterService"> <wsdl:port name="WSHttpBinding IUserRegisterService" binding="tns:WSHttpBinding IUserRegisterService"> <soap12:address location="http://localhost:8080/UserRegisterService" /> <wsa10:EndpointReference> <wsa10:Address>http://localhost:8080/UserRegisterService</wsa10:Address> <Identity xmlns="http://schemas.xmlsoap.org/ws/2006/02/addressingidentity"> <Dns>localhost</Dns> </Identity> </wsa10:EndpointReference> </wsdl:port> </wsdl:service> Listing 4-6.
