I want to create my first project, i created an Android Application but i want to add a Share Project, I went to Add New Project => .NET => Shared Project c#, I think this is the way to add a Shared Project.
The project only have a file: MyClass.cs.
My question is, how can I add the Reference folder?? Like here: developer.xamarin.com/guides/cross-platform/application_fundamentals/building_cross_platform_applications/case_study-tasky/#Shared_Core_Code
Thanks in advance.
