Walkthrough on creating WCF 4.0 Service and Hosting in IIS 7.5


This article will give step by step walkthrough

1. How to create a basic WCF 4.0 Service?

2. How to host WCF Service in IIS 7.5?

3. Hot to test service in a client.

Create WCF Service

Create WCF service. Open visual studio select new project and then from WCF tab select WCF Service application to create a new WCF service.


Delete the default code created by WCF from IService1 and Service1.svc.cs

a. So delete the data contract

b. Modify the service contract as below. Just make one operation contract to return a string .


using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
namespace WcfService5
    public interface IService1
        string GetMessage();



using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace WcfService5
    public class Service1 : IService1
        public string GetMessage()
            return "Hello From WCF Service ";

Leave the default configuration created by WCF.


    <compilationdebug="true"targetFramework="4.0" />
    <serviceHostingEnvironmentmultipleSiteBindingsEnabled="true" />

Host WCF Service in IIS 4.0

Open IIS

a. Open the command prompt in administrator mode. To do click on Start button then type RUN in search and then in Run window type inetmgr to open IIS .


Now you will have IIS open like below


b. Right click on Sites and then click Add Web Site


c. Now a window will open.


Give any name of your choice as the site name. I am giving name here HostedWcfService


Now click on select and choose ASP.Net v4.0 from the drop down.


Now in the physical path section, we need to give physical path of the service. So to get the physical path of the service, right click on the WCF Service project in visual studio and click open project in windows explorer. Open the project in windows explorer and from address bar copy the path and paste that below. Or you can browse also. Just click on browse button and navigate to project folder of the WCF Service.


Now at the Binding section select HTTP. Give any port number. I am selecting the port as 4567


Do not give any name as host name. Leave it blank


Check the check box Start Web Site Immediately.


And now click OK on the window.

d. Now open visual studio command prompt in administrator mode. Right click and select as administrator



Type the below command

aspnet_regiis.exe /iru


You will get the message Finished Installing ASP.Net 4.0

e. Now go to inetmgr, you would able to see the site you just created in previous step.


Publishing the WCF Service

Go back to WCF Service. Right click and select Publish


On clicking of publish a window will come.


Give a Service URL. You are free to give any Service URL here. Just make sure host name is geeting resolved. In stead of localhost you can give IP address or your machine name also.


Give the name of the site HostedWcfService. We created this site in previous step.


Leave the credential inactive.


Now click on Publish.


You will get the message in bottom publish succeeded

Browsing the service hosted in IIS

Open Inetmgr and right click on site HostedWcfService. Then from Manage Web Site select Browse option.


When you click on browse site will get open in browser


You will get the above error. Just in address bar append Service1.svc with the address to open the service in browser.


And in browser you will get the service up and running.


So now you successfully created and hosted the WCF 4.0 service in IIS 7.5

Testing the Service at client

a. Create console application project.


b. Right click and add the service reference.


c. Give in address the address of service hosted in IIS and click GO.


d. Call the service as below ,


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ConsoleApplication1.ServiceReference1;

namespace ConsoleApplication1
    class Program
        static void Main(string[] args)
            Service1Client proxy = new Service1Client();

  8. Okay, after reading countless web sites, this is the one that got it to work for me. Thanks so much for posting it.

  9. Hi,
    Thanks, I worked 100% on the local PC, but I’ve tried to use the client on another PC on the LAN, but the following message is displayed:

    There was no endpoint listening at that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

    What is this message?

    Thanks in advance

    Thanks. After a few other failed attempts from other how to’s I stumbled upon yours. I don’t know if
    the starts were aligned by then but it worked. Its good to see something work. Off to the next mountain :)

  11. Seriously i spent half day trying to deploy and this was piss easy!

    Question: Does Service Url needs to have different port number specified or can it be the same.
    When do I need this. For checking if service is published I can use localhost and port specified when App dir was set

  12. I keep getting WcfService5.Service11′ does not implement interface member ‘WcfService5.IService1.GetMessage()’

    Am I missing anything here.


  13. Man OH MAN….

    I am sure every one should agree that the folks at MSFT should be taking a look at this and seriously learning from it. The example on their page is simply mediocre at best

    Words cannot express how grateful I am for such a step by step, complete well rounded and well explained tutorial. Thank you so so so much.

  15. Thanks for such detail article. I have followed and being able to get to the part where we get the WSDL definition. I am running into problems with getting metadata, both wfctestclient and the console app complain about this fact. If you can clarify why this happening is I will appreciate it. My email is macs@conssoft.net and again, thanks for sharing such a useful piece of information.

  20. Everything works fine until I get to “Add Service Reference”. I did everything exactly as specified in the walkthrough. When I follow the “Add Service Reference” procedure I get an error message as follows: “There was an error downloading metadata from the address. Please verify that you have entered a valid address.” – (yes, I’m positive the address is valid), And the Details section starts with “Metadata contains a reference that cannot be resolved: ‘http://localhost:4567/Service1.svc?wsdl’, and then later in the Details, “There was an error downloading ‘http://localhost:4567/Service1.svc?xsd=xsd0’. The underlying connection was closed: An unexpected error occurred on a receive.”
