This gist uses a custom JsonConverter to support derived types in ASP.NET Core 3 requests and responses. By default, .NET Core
does not support derived types in JSON serialization; the properties of derived types are not serialized in responses, and in
requests there is inherently a lack of support in JSON for identifying inherited types.

To implement this code in your project:
  1. Copy the DerivedTypeJsonConverter class below into your project.
  2. For each of your base types, create a class that derives from DerivedTypeJsonConverter. Follow the MyResultJsonConverter
     example below.
