VS2019 How to add WSDL to plugin and reference endpoint configuration name.

I an using Nop 4.0, and VS 2019.  I added a Connected Service to the plugin.  I am attempting to write a method to call the service client and get information from outside source.  
I have this inside of method.  Private static BKOR_PWSClient wrkClient = new BKOR_PWSClient();
I cannot access anything inside the wrkclient.

I am not sure that importing a WSDL file as a Connected Service creates all the files needed in VS2019.
A References.cs file was created.

One note - I imported the WSDL file, and did not have the WCF actually connect to outside url.  Not sure if that makes any difference.

Anyone have suggestions?
