Cannot get the WCF Test Client to work

I am using the WCF Test Client. When I go to 'add service' and select a service to add I get this message,

Assembly Microsoft.ApplicationServer.Hosting, Version 1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 was not found. Reinstall the assembly or Visual Studio. The application cannot continu开发者_JAVA技巧e and will exit.

The service I am using is on the web, i.e. it is not being hosted locally on my machine. It is also using https.

Any ideas?

You should reinstall the Microsoft.ApplicationServer.Hosting (or Visual Studio), as this assembly is missing. This has nothing to do with the web service, the assembly to consume a service is not installed.
