I\'m using Visual Studio to try out Xamarin.Forms. I\'m trying to follow the guide: http://developer.xamarin.com/guides/cross-platform/xamarin-forms/xaml-for-xamarin-forms/getti
I have been having the same issue now and then, and this is what I have been doing to fix it: When in the PCL project, I add a new cross-platform XAML page to the project. Adding a new XAML page takes a few seconds for the references to "hook". After the new XAML page is successfully added to the project, the red underlines on the XAML Pages (with issues) will get cleared. Once the problem is solved, I simply delete the XAML file that I have just added. - So, in summary, adding a new XAML page then deleting it has been solving the issue for me.
