Hosting WCF Service

There are some ways to hosting WCF service as below:

1. IIS; 2. Console App; 3. Window Service

Using Console Application to host WCF service:

Step 1:

 

Step 2: Add a Class Library project : 'Contract'

Step 3: Add a Interface : 'IHelloWorld'

using System.ServiceModel;

namespace Contract
{
    [ServiceContract(Name = "HelloWorldService")]
    public interface IHelloWorld
    {
        [OperationContract]
        string SayHello();
    }
}

Step 4: Add a Class : 'HelloWorld'

namespace Contract
{
    public class HelloWorld : IHelloWorld
    {
        public string SayHello()
        {
            return "Hello World. I'm WCF Service.";
        }
    }
}

Step 5: Add a Console Application : 'Host'

Step 6:
Use WCF Service Configuration Editor to generate the server config.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="HelloWorldBehavior">
                    <serviceMetadata httpGetEnabled="true" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <services>
            <service behaviorConfiguration="HelloWorldBehavior" name="Contract.HelloWorld">
                <endpoint address="http://localhost:9999/HelloWorldService" binding="basicHttpBinding"
                    bindingConfiguration="" contract="Contract.IHelloWorld" />
                <host>
                    <baseAddresses>
                        <add baseAddress="http://localhost:9999/HelloWorldService" />
                    </baseAddresses>
                </host>
            </service>
        </services>
    </system.serviceModel>
</configuration>

Step 7:
Set up server host

using System;
using System.ServiceModel;
using Contract;

namespace Host
{
    class Program
    {
        static void Main(string[] args)
        {
            using (var host = new ServiceHost(typeof(HelloWorld)))
            {
                host.Opened += delegate
                                   {
                                       Console.WriteLine("CalculaorService已经启动，按任意键终止服务！");
                                   };
                host.Open();  
                Console.Read();
            }
        }
    }
}
