Unable to add Xamarin.Android and Xamarin.iOS to P

问题:

I'm trying to workout a sample project using MvvmCross, but I'm stuck with the first step of adding the frameworks in VS2012.

When I try to add Xamarin.Android and Xamarin.iOS framework in a PCL project, it is showing an error

There is no available functionality that is portable between the frameworks you have selected

I tried following the steps in this answer, but it didn't worked.

Can someone shed some light on this issue.

Thanks.

Recent (mainly good) changes from Microsoft mean that the platforms that can officially be used together is now set to:

• sl5
• wp8
• winstore
• wpf with .net 45
• the xam twins

To support these try the 3.1.1 release from Mvvmcross - currently available in beta as Try the beta packages - 3.1.1-beta5 - use "include prerelease" in nuget.
