If you are new to WCF services then please read my earlier blogs. Go through with this link - WCF Tutorial step by step.

WCF supports a various way to host a service. In this blog, I will explain about Hosting a WCF Service in IIS.

How to host WCF service in IIS?


Step 1: Create a WCF Library project in Visual Studio.
Step 2: Delete Class and Interface which is created by default.
Step 3: Create an interface IProduct. Add one operation contract in this.
    [ServiceContract]
    interface IProduct
    {
        [OperationContract]
        string GetProduct(int productId);

    }
Step 4: Add a class Product.cs to implement this interface.
class Product: IProduct
    {
        public string GetProduct(int productId)
        {
            return "Product Id - " + productId + "is available at store";
        }
    }



Step 5: Right click on Solution in Visual Studio. Add a new website in the same solution. Select WCF Service.

Step 6: Delete files from App_Code. Add the reference of the WCF service project.

Step 7: Open .SVC file and remove code behind. .SVC file should look like this.
<%@ ServiceHost Language="C#" Service="WcfServiceLibraryMaster.Product" %>

Step 8: Now host your WCF service in IIS. Open IIS. Right click on Default web site and add an application. You may also create an independent site in IIS.



Step 9: Fill all the details.


Step 10: Once done. Right click on newly added Application or Website and select Switch to content view. You can see your service file there.


Step 11: Browse your file and you will see an output like this.



Step 12: Now it's time to consume the WCF service.
Step 13: Add a new Website in the same solution. Create ASP.Net website.
Step 14: Add service reference in this website.(Browse the .svc file in IIS and copy the URL, right click on Website and add Service Reference.) 



Step 15: Once Service Reference added. You write code to consume WCF service that you created.
WCFServiceReference is the name which I gave while adding WCF service reference.

         WCFServiceReference.ProductClient objClient = new WCFServiceReference.ProductClient();
       string ss = objClient.GetProduct(1001);
       Response.Write(ss);

Step 16: Your output will.

1001 is the Product Id which was passed from the client.

Product Id - 1001 is available at store
