The provided URI scheme 'https' is invalid

Question

I have tried implementing a number of suggestions from other questions to fix this frustrating issue. Normally, when I set up a site in IIS, the web apps are somewhat "agnostic" to what is going on at the transport layer. However, for this particular app, I cannot get it to work when I apply an https binding.

My web.config looks like:

<system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
    <bindings>
      <basicHttpBinding>
        <binding name="DefaultAPIBinding">
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None" realm="" />
            <message clientCredentialType="Certificate" algorithmSuite="Default" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
  </system.serviceModel>

and my Global.asax.cs looks like

 ContainerBuilder builder = new ContainerBuilder();

  //builder.Register<IContactRepository, ContactRepository>();
  builder.Register<IResourceFactory, Classes.LightCoreResourceFactory>();

  IContainer container = builder.Build();

  var configuration = HttpHostConfiguration.Create().SetResourceFactory(new LightCoreResourceFactory(container));  

  RouteTable.Routes.MapServiceRoute<WebServiceResources>("ws", configuration);

But whenever I add an https binding to my IIS site, I get the error:

The provided URI scheme 'https' is invalid; expected 'http'.
Parameter name: context.ListenUriBaseAddress

[ArgumentException: The provided URI scheme 'https' is invalid; expected 'http'.

Since the error message does not provide a location in my code to check or any other hints, and since I have already implemented some of the other suggestions on how to fix this, I am at a loss. Any idea of what I can do to make this app allow https bindings?

To elaborate on what @thedr said, here is what we did:

1. Upgrade to MVC4 if you have not done so already
2. Add the following class ripped straight from this CodePlex discussion

public class HttpsServiceHostFactory : HttpConfigurableServiceHostFactory
{
    public override ServiceHostBase CreateServiceHost(string constructorString, Uri[] baseAddresses)
    {

        var host = base.CreateServiceHost(constructorString, baseAddresses);

        foreach (var httpBinding in from serviceEndpoint in host.Description.Endpoints
                                    where serviceEndpoint.ListenUri.Scheme == "https"
                                    select (HttpBinding)serviceEndpoint.Binding)
        {
            httpBinding.Security.Mode = HttpBindingSecurityMode.Transport;
        }

        return host;
    }
}

Then when you do RouteTable.Routes.MapServiceRoute, it should look like

RouteTable.Routes.
        MapServiceRoute<WebServiceResources, HttpsServiceHostFactory>("ws", configuration);
