WCF – IIS Hosting
”;
Hosting a WCF service in IIS (Internet Information Services) is a step-by-step process. IIS Hosting is illustrated below in detail with the desired coding as well as screenshots to understand the process.
Step 1 − Start Visual Studio 2012 and click File → New → Web site. Select “WCF Service” and Location as http. This will host the service in IIS. Click OK.
Step 2 − The code behind the interface is given below.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
// NOTE: You can use the "Rename" command on the "Refactor" menu to
// change the interface name "IService" in both code and config file
// together.
[ServiceContract]
Public interface IService {
[OperationContract]
String GetData(int value);
[OperationContract]
CompositeType GetDataUsingDataContract(CompositeType composite);
// TODO: Add your service operations here
}
// Use a data contract as illustrated in the sample below to add
// composite types to service operations.
[DataContract]
Public class CompositeType {
Bool boolValue = true;
String stringValue = "Hello ";
[DataMember]
Public bool BoolValue {
get { return boolValue; }
set { boolValue = value; }
}
[DataMember]
Public string StringValue {
get { return stringValue; }
set { stringValue = value; }
}
}
Step 3 − The code behind the class file is given below.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
// NOTE: You can use the "Rename" command on the "Refactor" menu to
// change the class name "Service" in code, svc and config file
// together.
Public class Service : IService {
Public string GetData(int value) {
Return string.Format("You entered: {0}", value);
}
Public CompositeType GetDataUsingDataContract(CompositeType composite) {
if(composite == null) {
thrownewArgumentNullException("composite");
}
if(composite.BoolValue) {
composite.StringValue += "Suffix";
}
return composite;
}
}
Step 4 − Service file (.svc) contains the name of the service and the code behind the file name. This file is used to know about the service.
<%@ ServiceHost Language = "C#" Debug = "true" Service = "Service" CodeBehind = "~/App_Code/Service.cs" %>
Step 5 − Server-side configurations are mentioned in the config file. Here, there is a mention of only one end-point which is configured to ”wsHttpBinding”; we can also have multiple endpoints with different bindings. Since we are going to host in IIS, we have to use only http binding.

Step 6 − You need to mention the service file name, along with the Address mentioned in the config file. The screenshot of IIS is given here.
Click Start → run → inetmgr which will open the following window.
Step 7 − Run the application which will produce the following screen.
