[csharp] How can I tell generated code to ignore certificates

I used swagger-codegen to generate C# classes that, among other things, log into an application. However, I the login to work because the site I'm connecting to uses a self-signed certificate. I've hunted around the Web and found the most common answer is to add this to my code:

ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;

But this doesn't work, or at least it doesn't work for me. Should this work with the code generated from swagger-codegen or is there another way to tell the underlying web framework to ignore certificate errors?

I'm using swagger-codegen version 2.4.18-SNAPSHOT with .NET Core V5.0.

Thanks

Start by examining the generated C# client and how it performs requests under .NET Core 5.0, then compare that behavior with the certificate-validation callback described in the issue. Done means identifying whether the generated client supports configuring certificate validation and documenting the applicable configuration or limitation.
