title: Error while adding WCF service as connected service in .net core 2.0 web application
body: <p>I am using VS 2017, when I try to add WCF service as a connected service in asp.net core web application using "Microsoft WCF Web Service Reference Provider", it errors out, here are the error logs:</p>
  
  <pre><code>Importing web service metadata ...
  Number of services found: 1
  Restoring NuGet packages ...
  Building solution ...
  Scaffolding service reference code ...
  Warning: Cannot import wsdl:binding
  Detail: An exception was thrown while running a WSDL import extension: System.ServiceModel.Channels.StandardBindingImporter
  Error: The method or operation is not implemented.
  
  Error:Error: No endpoints compatible with .Net Core apps were found.
  
  
  Error:An unknown error occurred while invoking the service metadata component.
  Failed to generate service reference.
  </code></pre>
  
  <p>Anybody, workaround for this issue?</p>
  
  <p>I am able to add these WCF services in .net framework applications successfully.</p>
  
  <p>Edit 1: Tested again with VS 15.5.1, still not working. So .Net Core does not fully support message security: <a href="https://github.com/dotnet/wcf/issues/1354" rel="nofollow noreferrer">https://github.com/dotnet/wcf/issues/1354</a>
  I have message security in WCF, so this makes sense why I am not able to add my WCF service as connected service in .Net core project.</p>
