I'm trying to invoke a soap web service from .NET Core.

I've built the proxy using dotnet-svcutil and found it's a lot different from an older .NET 4.6 implementation of the same endpoint.

The .NET Core proxy doesn't have a class that inherits from System.Web.Services.Protocols.SoapHttpClientProtocol. I understand this namespace is gone in .NET Core, but what has replaced it?
