Failed to add cocossharp.forms in visual studio 2017

Question

I created a xamarin.forms project in visual studio 2017, then I tried to add cocossharp.forms using nuget and I got this error:

Could not install package 'CocosSharp 1.7.1'. You are trying to install this package into a project that targets '.NETPortable,Version=v4.5,Profile=Profile259', 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.

It seems I got the same error in create a cocossharp project in xamarin, but the answer provided is for xamarin studio and I don't know how to apply that to visual studio.

You have to open the project's .csproj file as text and change the targeted profile to 151 and the targeted framework version to 4.6

Here is what the lines you need to update look like:
