public:
 virtual void OnStarting(Func<System::Threading::Tasks::Task ^> ^ callback);
public virtual void OnStarting (Func<System.Threading.Tasks.Task> callback);

Public Overridable Sub OnStarting (callback As Func(Of Task))

Parameters

callback

Callbacks registered here run in reverse order. The last one registered is invoked first. The reverse order is done to replicate the way middleware works, with the inner-most middleware looking at the response first.
