I was under the impression that Xamarin.Forms.Maps was PCL compatible, but when trying to Install it via NuGet for a PCL, I get the following NuGet error:
Attempting to resolve dependency 'Xamarin.Forms (≥ 1.4.2.6355)'.
'Xamarin.Forms.Maps 1.4.2.6355' already installed.
Adding 'Xamarin.Forms.Maps 1.4.2.6355' to .
Could not install package 'Xamarin.Forms.Maps 1.4.2.6355'. You are trying to install this package into a project that targets 'portable-net45+win+wpa81+MonoAndroid10+xamarinios10+MonoTouch10', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
Not sure if it matters, but I'm on Visual Studio 2013.
The PCL targets:
.NET Framework 4.5
Windows 8
Windows Phone 8.1
Xamarin.Android
Xamarin.iOS
Xamarin.iOS (Classic)
