data binding - For MVVM in Xamarin.Forms, which is better? Common views or Platform specific views? -

i'm starting xamarin. wanted know approach more suitable mvvm xamarin.forms app:

1. keeping user interface views common ios, android , wp8.1 or platform specific?
2. which 1 easier (as there's no ui designer xamarin's xaml)?
3. which 1 easier data binding?

there several questions within post:

keeping user interface views common ios, android , wp8.1 or platform specific?

this entirely dependent on trying achieve. xamarin.forms usable option whole range of solutions not 'catch all' solution. read on limitations , make decision based on project's requirements.

which 1 easier (as there's no ui designer xamarin's xaml)?

all of options carry own particular learning curve , there no right or wrong answer. irrespective of approach take there requirement understand underlying native implementation.

which 1 easier data binding?

the implementations have described have no bearing on how utilise data bindings.

i recommend reading through developer documentation on xamarin site , making informed decision on how proceed.
