WCF Instance App

with a brief introduction to WCF in the previous article, here's a small example of how to build and apply a WCF application. 1. Add a WCF service: 2. Open the newly created service interface Ishowmyname and add the method (be careful not to discard the service tag or access it):
    
3. Add a method to implement the service:
    
4. Look in the browser as shown to indicate success:
    
5. Publish it in IIS so that the server is configured.
6. Client configuration, the first thing to do is to add the configuration file:(1 ) Configure the Web. config

< Configuration >

< system.web >

< compilation Debug="true" targetframework="4.0" />

< Endpoint

contract="contracts.ishowmyname"

</ Client >

</ System.ServiceModel >

</ Configuration >

(2) client Invoke service

To add a reference to the client:

using System.ServiceModel.Channels;

Using System.ServiceModel ;          You can then add code to invoke the WCF service:
// because the service is created through a channel factory, it is necessary to instantiate the channel factory first

ChannelFactory <ishowmyname> Factory = new channelfactory <ishowmyname>("Basichttpbinding_ishowmyname");

ishowmyname MyObject = Factory. CreateChannel ();

Methods for invoking a service

string time = Myobject.showname (this. txtname.text);
