Status:

• OpenAPI generation:
  • Swashbuckle is actually died and not support polymorphism, Swashbuckle.AspNetCore actively maintained, but still not support ([1], [2]) polymorphism.
    • Third-party nuget available for ASP.NET Core version
    • Possible we may write our own implementation for Swashbuckle for ASP.NET
  • NSwag support polymorphism
• UI:
  • swagger-ui: has no support and has no plans to implement in near future
  • ReDoc: support polymorphism, but have no built-in console
• Code generation:
  • AutoRest: support polymorphism
  • NSwag can also be used for generation

Resolution: the blocking issue is UI support: swagger ui has no support of polymorphism, while ReDoc has no built-in console. For OpenAPI generation we may have a few solutions, code generation already ready for polymorphism and not require any additional actions.
