c# - Cannot get the WCF Test Client to work -

I am using a WCF test client when I go to 'add service' and select a service to add I get this message, I get this message,

Assembly Microsoft Application server. Hosting, Version 1.0.0.0, Culture = Neutral, Public Token = 31bf3856ad364e35 was not found. Restore the assembly or the visual studio The application can not continue and will exit.

The service I am using is on the Web, that is, it is not being hosted locally on my machine. It's also using https.

Any thoughts?

You Microsoft.ApplicationServer.Hosting (or Visual Studio) because it The assembly is unavailable. There is nothing to do with the web service, the assemblies are not installed to consume the service.
