Hosting two WCF services using a single console app

Question

I am trying to host two services using a single console app. However, when I am trying to do so, only one service gets hosted, while the other does not.

Program.cs:

namespace WWWCFHost
{
    class Program
    {
        static void Main(string[] args)
        {
            using (ServiceHost host = new ServiceHost(typeof(WWWCF.Login)))
            {
                host.Open();
                Console.WriteLine("Service1 Started");
            }
            using (ServiceHost host1 = new ServiceHost(typeof(WWWCF.UserRegistration)))
            {
                host1.Open();
                Console.WriteLine("Service2 Started");
                Console.ReadLine();
            }
        }
    }
}

App.config

<configuration>
  <system.serviceModel>

    <services>
      <service name="WWWCF.Login" behaviorConfiguration="WWWCF.mexBehaviour1">
        <endpoint address="Login" binding="basicHttpBinding" contract="WWWCF.ILogin">
        </endpoint>

        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange">
        </endpoint>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8080"/>
          </baseAddresses>
        </host>
      </service>

      <service name="WWWCF.UserRegistration" behaviorConfiguration="WWWCF.mexBehaviour2">
        <endpoint address="UserRegistration" binding="basicHttpBinding" contract="WWWCF.IUserRegistration">
        </endpoint>

        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange">
        </endpoint>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8090"/>
          </baseAddresses>
        </host>
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior name="WWWCF.mexBehaviour1">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
        <behavior name="WWWCF.mexBehaviour2">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>

  </system.serviceModel>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
  </startup>
</configuration>

As in the code above, I am trying to host one service on port 8080 and the other on port 8090. When I run the application, the first service starts and then closed automatically and the second service remains started. How can I host both the services simultaneously ?

I have gone through the link : Two WCF services, hosted in one console application

I have gone through other threads as well.But they do not solve my issue.

Will be happy to provide any further details if required.

Your first service jumps out of the using block and so is disposing too early. Try this...

using (ServiceHost host = new ServiceHost(typeof(WWWCF.Login)))
using (ServiceHost host1 = new ServiceHost(typeof(WWWCF.UserRegistration)))
{
     host.Open();
     Console.WriteLine("Service1 Started");

     host1.Open();
     Console.WriteLine("Service2 Started");
     Console.ReadLine();
 }
