NET 9: How can I generate a client using the default OpenApi specification (.MapOpenApi()) instead of the NSwag.AspNetCore lib?

[jonataspc]

Given I use documentGenerator=aspNetCoreToOpenApi, basically I need to generate a C# client for a .NET 9 Web API project that uses the default OpenAPI generator.
I don't want to add the NSwag.AspNetCore lib, because it doesn't understand correctly the TypedResults result types.

Is that possible?
