TokenClient Error following .Net 4.x Tutorial

I have a legacy .Net 4.5.1 Web Form App that I’m trying to build Okta into. I followed the directions in the following blog exactly:

I’m getting several errors in the Startup.cs class. They all are around creating the TokenClient class. It wants only two parameters, but the example gives three. I have a feeling this Startup.cs class is from MVC and causing this error? I’m not sure. Here is the code:

var tokenClient = new TokenClient($"{_authority}/v1/token", _clientId, _clientSecret);

Error => ‘TokenClient’ does not contain a constructor that takes 3 arguments

The signature it calls for is TokenClient(HttpMessageInvoker, TokenClientOptions)

Can anyone help?
