Creating WCF Service

I am new in WCF. I have created a wcf service application and in it there is an interface and class.

My Interface:

using System.ServiceModel;

namespace WcfService1
{   
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string Display();        
    }    
}

My class:

namespace WcfService1
{
    public class Service1 : IService1
    {
        public string Display()
        {
            return "Hello";
        }
    }
}

Now when i am running this service in the browser. The following screen is coming after clicking on the Service1.svc

enter image description here

Ho do I access the Display() on the browser?

After followed the first answer, the following is coming:

I think you're looking for WebGet if you want to access it through your browser.

using System.ServiceModel;
using System.ServiceModel.Web;

namespace WcfService1
{   
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        [WebGet(RequestFormat = WebMessageFormat.XML, ResponseFormat = WebMessageFormat.XML, UriTemplate = "/display/")]
        string Display();        
    }    
}

Add these behaviours

<behaviors>
  <serviceBehaviors>
    <behavior name="ServiceBehaviour">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="web">
      <webHttp />
    </behavior>
  </endpointBehaviors>
</behaviors>

Add this endpoint address

  <service behaviorConfiguration="ServiceBehaviour" name="WCFService1.Service1">
      <endpoint address="" behaviorConfiguration="web" binding="webHttpBinding"
      bindingConfiguration="b_WebHttpBinding" contract="WCFService1.IService1" />
  </service>

Add this binding

<bindings>
  <webHttpBinding>
    <binding name="b_WebHttpBinding" closeTimeout="00:01:00"
        openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
        allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
        maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" transferMode="Buffered"
        useDefaultWebProxy="true" crossDomainScriptAccessEnabled="true">
      <readerQuotas maxDepth="32" maxStringContentLength="2147483647" maxArrayLength="2147483647"
          maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
      <security mode="None">
        <transport clientCredentialType="None" proxyCredentialType="None"
            realm="" />
      </security>
    </binding>
  </webHttpBinding>
</bindings>

Now you should be able to call your service like 

http://localhost:22727/Service1.svc/display/

Then it should display a string in XML Format (you can change it to JSON if you like)

Also, make sure you reference the following libraries

System.ServiceModel.Web
System.Web.Extensions
System.Web.Services
System.Web

Split your Solution into two projects:

  • New Project -> WCF -> WCF Service Library
  • New Project -> WCF -> WCF Service Application

The "Service Application" is your web project containing the svc endpoint. The "Service Library" is a class library containing your services.

When you run (F5) the service library project, Visual Studio will start the WCF Test Client (WcfTestClient.exe), giving you a quick interface to test your services.

The .svc endpoint in your web project does not give you a built-in test interface (similar to the way it worked in the asmx days).
