Answer 1

namespace BaseLibrary
{
    [Export("base",typeof(AppSettingsDefaultImpl))]
    class AppSettings : AppSettingsDefaultImpl
        {
            public override string getAppName()
            {
                return "ABC";
            }

        }
}

namespace ChildApp1
{
    [Export("child",typeof(AppSettingsDefaultImpl))]
    class AppSettings : AppSettingsDefaultImpl
        {
            public override string getAppName()
            {
                return "ABC";
            }

        }

Then:

CompositionContainer container;// override MefBootstrapper

AppSettingsDefaultImpl appSettings = 
    container.GetExport<AppSettingsDefaultImpl>("child");
