Fwiw, anyone using this guide with .NET Core 3 Preview (or otherwise) will have a bad time. The Newtonsoft.Json breaking change kills Microsoft.AspNetCore.Authentication.OAuth’s claim handling causing the OpenIdConnect’s authentication handler to die in a blazing fire when attempting to handle ClaimActions.
Manually referencing 2.0.0 in the Server project doesn’t work either. Forking, dropping all projects except Okta.AspNet.Abstractions and Okta.AspNetCore, and swapping things over to 3.x.x-preview and netcoreapp3.0/netstandard3.0 does work. It’s just a pain.
