Unable to create a nuget package out of a custom control in xamarin forms

I just created a simple custom control in my xamarin.forms project and want to use the same control as a nuget package in my other projects. After creating the .nupkg file I tested it by adding as a local package in another xamarin forms project.The issue is the package I created is installed,but the contents inside it are not available.. Can anyone help me on resolving this..
