OpenAPI support

[Rikarin]

Hi,
can you add support for OpenAPI https://learn.microsoft.com/en-us/aspnet/core/fundamentals/openapi/overview?view=aspnetcore-9.0 as swagger seems to not be the default API explorer anymore.

At this time, we do not have any plans to add OpenAPI support.
This is because ASP.NET Core OpenAPI support is only available in .NET 9 (STS) and later.

However, there is a possibility that we will support it in the future.
