Screenshot of the error after building

With a clean install of Xamarin, when I create a new Xamarin.Forms (Portable) project in Visual Studio 2015 on Windows 10 I get the following popup message:

Package Installation Error Could not add all required packages to the project. The following packages failed to install from 'C:\PROGRAM FILES (X86)\MICROSOFT VISUAL STUDIO 14.0\COMMON7\IDE\EXTENSIONS\XAMARIN\XAMARIN\3.11.15 89.0\Packages':

Xamarin.Forms. : Could not install package 'Xamarin.Forms'. You are trying to install this package into a project that targets '.NETPortable,Version=v4.5,Profile=Profile111', 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.

After that I get the warning:

Unexpected error - Please file a bug report at http://bugzilla.xamarin.com. Reason: System.IO.FileNotFoundException: Could not load assembly 'portable, Version=, Culture=neutral, PublicKeyToken='. Perhaps it doesn't exist in the Mono for Android profile?	portable.Droid		

When selecting the android project as Startup, I build it and I got this above warning as error, with additional errors such as: 'App.OnResume();' no suitable methods found to override.

What should I do?

I believe this may be related to #35952 as people are having similar issues.
Comment 2 Jason Smith [MSFT] 2016-04-13 19:31:21 UTC
This should be fixed in the latest version of the VS templates available in the Xamarin beta channel.
