I'm developing mobile app in Xamarin.Android with MvvmCross. In my app, I want to add simple button. When user clicks this button, it should open a dialog fragment window when I could put controls etc. (example: http://1.bp.blogspot.com/-cSiHQETCeNY/VlQUtoMC2PI/AAAAAAAABJ0/_yWy0coWpqw/s1600/CustomAlert_3.png). I know how to do this in xamarin.android but dont know how in mvvmcross PCL project ViewModels (not android ui one). I'm confused about samples and similar question, and seek for the best solution. Anyon could help?
