View-models with Xamarin native

After we add the libraries, let's start with the AudioPlayer.Portable project. Create a new folder called ViewModels, and add a new file called MainPageViewModel.cs. Let's start implementing our first view-model with MVVMCross:

namespace AudioPlayer.Portable.ViewModels 
{ 
    using MvvmCross.Core.ViewModels; 
 
    public class MainPageViewModel : MvxViewModel 
    { 
        public MainPageViewModel() 
        { 
        } 
   } 
} 

When we built our Xamarin.Forms view-models, we created our own base view-model for handling property changes; using this library we can cut a few corners with base properties. MvxViewModel has a similar implementation with handling property changes; for our MainPage, we are going to develop the same first page as the last chapter, so let's start with the private properties:

public class MainPageViewModel : MvxViewModel 
    { 
        #region Private Properties 
 
        private string _descriptionMessage = "Welcome to the Music...
