Correct handling of WCF files and solutions
(1) WCF programming: create a new WCF service application project Ch45Ex01 under the directory C:BegVCSharp\ Chapter35
(2) WCF programming: add a console application Ch45Ex01Client to the solution.
(3) WCF programming: click the Build Solution option on the Build menu.
(4) WCF programming: right-click Ch45Ex01Client in Solution Explorer and select the Add Service Reference option.
(5) WCF programming; in the Add Service Reference dialog box, click Discover.
(6) WCF programming: start developing the Web server. After loading the information of the WCF service, expand the reference and view its details, as shown in the figure
(7) WCF programming: click the OK button to add a service reference.
(8) WCF programming: modify the code in Pragram.cs in the Ch45Ex01Client application, as follows:
Using System
Using System.Collections.Generic
Using System.Linq
Using System.Text
Using Ch45Ex01Client.ServiceReference1
Namespace Ch45Ex01Client
{
Class Program
{
Static void Main (string [] args)
{
String numericInput = null
Int intParam
Do
{
Console.WriteLine (
"Enter an integer and press enter to call the WCF service."
NumericInput = Console.ReadLine ()
}
While (! int.TryParse (numericInput, out intParam))
Service1Client client = new Service1Client ()
Console.WriteLine (client.GetData (intParam))
Console.WriteLine ("Press an key to exit.")
Console.ReadKey ()
}
}
}
