-In controller-based apps, metadata is collected from attributes like [`[EndpointDescription]`](xref:Microsoft.AspNetCore.Http.EndpointDescriptionAttribute), [`[HttpPost]`](xref:Microsoft.AspNetCore.Mvc.HttpPostAttribute),
-and [`[Produces]`](xref:Microsoft.AspNetCore.Mvc.ProducesAttribute).
-In minimal APIs, metadata can be collected from attributes, but may also be set by using extension methods
