Now that you have completed the EmployeeServer class library, let s create a console application that publishes the EmployeeServer on the network. To do so, create a new project of type console application. Add references to the System.Runtime.Remoting and EmployeeServer assemblies by using the Add Reference dialog box. At the top of the Main class, import two namespaces: System.Runtime.Remoting and EmployeeServer. Right-click on your project and add a new XML file named EmployeeServer.config. This XML file will contain markup necessary to configure the remoting infrastructure on the server side. Listing 11-3 shows the contents of the EmployeeServer.config configuration file. Listing 11-3. Configuring the Remoting Server < xml version="1.0" encoding="utf-8" > <configuration> <system.runtime.remoting> <application> <service> <wellknown type="EmployeeServer.Employee,EmployeeServer" mode="SingleCall" objectUri="MyRemoteObject"></wellknown> </service> <channels> <channel port="8088" ref="tcp"></channel> </channels> </application> </system.runtime.remoting> </configuration>

At the top it declares a variable of type User. The GetEmployees() web method fills a DataSet with all the records from the Employees table and returns the DataSet back to the caller. The important thing to note about the GetEmployees() web method is that it is decorated with the SoapHeader attribute. This is how you inform the web method that a SOAP header is to be processed. The SoapHeader attribute specifies one parameter and two properties. The first parameter specifies the instance name of the SOAP header class that we wish to use. In our example, the name of the User variable is CurrentUser and hence that is what we pass to the web method. This instance variable must be available publicly in the web service class. The Direction property
