Need help about the complication in watchkit app

[AlancLiu]

I've already done the watch project with Xcode use Objective-C, when I want to did it with Xamarin, I got this problem.

My Xamarin Studio has already updated to the latest version(5.10.3 (build 51)), and my Xamarin.iOS version is 9.6.1.9 (Xamarin Business).
But I can't add complications When I add a new watchkit extension to my iOS project, because there is no options for "Include Complication", just has "Glance" and "Notification".(Like the picture)

And I am trying to add a complication by modify the .csproj file, but when I add the "ComplicationController.cs" to my project, I found I do not have the "ClockKit" library file.

So what should I do?
