在ASP.NET MVC应用中添加WCF服务引用失败

Question

I'm trying to add a WCF service to my ASP.NET MVC application. After setting it up, I get an error whenever I want to test it.

Here is my code:

BackgroundTask.svc

public class BackgroundTask : IBackgroundTask
{
    public void ShutdownVm()
    {
    }

    public void UpdateTable()
    {
    }
}

IBackgroundTask.cs

[ServiceContract]
public interface IBackgroundTask
{
    [OperationContract]
    void ShutdownVm();
    [OperationContract]
    void UpdateTable();
}

Web.config

  <system.serviceModel>
    <services>
      <service behaviorConfiguration="bgtBehaviour" name="IsolutionsAzureManager.Controllers.BackgroundTask">
        <endpoint address="BackgroundTask" binding="basicHttpBinding"
          bindingConfiguration="" name="" contract="IsolutionsAzureManager.Controllers.IBackgroundTask" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:44304/" />
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="bgtBehaviour">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

So, whenever I want to test my WFC service, I get this error: Error: Cannot obtain Metadata from https://localhost:44304/Controllers/BackgroundTask.svc

Error: The HTML document does not contain Web service discovery information.

Can anyone see the mistake?

Because you are attempting to acquire the mex endpoint over Https, you'll also need to switch to mexHttpsBinding and to enable the httpsGetEnabled setting:

 <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />

Alternatively, obtain the endpoint via http ( http://localhost:44304/Controllers/BackgroundTask.svc ) and then just switch back to https once the client has built the service reference artifacts.
