Error in deploying WCF service on WPF application

Question

I am working on WCF application, starting simple HelloWorld service. I have develop simple WPF application to host services, i.e. start and stop service

when I try to test this service with url "http://localhost:8087/MyServices/HelloWorldService" on WCFTestClient, I am getting following error

Error: Cannot obtain Metadata from http://localhost:8087/MyServices/HelloWorldService If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address.

The security context token would be invalid if the service aborted the channel due to inactivity.

app.config

 <system.serviceModel>
<services>
  <service name="App.Services.Managers.HelloWorldManager">
    <endpoint address="HelloWorldService"
              binding="wsHttpBinding"
              contract="App.Services.Contracts.IHelloWorldService">
    </endpoint>
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8087/MyService"/>
      </baseAddresses>
    </host>
  </service>
</services>

C# class to open and close service

public class ServicesHostManager
{
    ServiceHost _helloWorldServicesHost = new ServiceHost(typeof(HelloWorldManager));

    public void ProcessHelloWorldService(string _process)
    {
        if(!string.IsNullOrEmpty(_process))
        {
            try
            {
                if (_process.Equals("open_service"))
                {
                    _helloWorldServicesHost.Open();
                }
                else if (_process.Equals("close_service"))
                {
                    _helloWorldServicesHost.Close();
                }
            }
            catch (Exception e)
            {
                System.Windows.MessageBox.Show(e.ToString());
            }
        }
    }

  <service name="App.Services.Managers.HelloWorldManager" behaviorConfiguration="DefaultServiceBehavior">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8087/MyService"/>
      </baseAddresses>
    </host>
    <endpoint address="HelloWorldService" binding="wsHttpBinding" contract="App.Services.Contracts.IHelloWorldService"></endpoint>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="DefaultServiceBehavior">
      <serviceMetadata httpGetEnabled="True" httpsGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="False" />
