How to install CocosSharp in Xamarin.Forms Protable project?

Question

I created a Blank App (Xamarin.Forms Portable). I set up and run HAXM, Android and iOS projects works great. I wanted to add a CocosSharp view, so I tried to install CocosSharp nuget package. But I'm getting this errors:

Is this another bug? How can I fix it? I just wanted to add a CocosSharp to default, blank Xamarin.Forms.

Thanks

EDIT: When I try to uncheck "Windows Phone Silverlight " I have an error:

The default (template created) Xamarin.Forms PCL-based project targets Profile259 and that includes SilverLight support which is not supported by CocosSharp.

Change your PCL-based project to Profile111 which removes Silverlight support and you will be able to add the CocosSharp package.
