New Extensibility Model for VS. How to add config page for extesion?

Question

 public class Options: DialogPage
 {
    [Category("1")]
    [DisplayName("Access Key:")]
 }

[VisualStudioContribution]
[ProvideProfileAttribute(typeof(Options), "Extension Name", "General", 0, 0, true)]
internal class ExtensionEntrypoint : Extension
{}

It is old implementation, which does not work. And the new model I can find example. Seems ProvideProfileAttribute/ ProvideOptionsPage can be applied just for package ExtensionEntrypoint: AsyncPackage. But what is the new method to add settings page?
