New Solution. This will open a dialog with Project Types on the left and some input fields on the right.Other you will see Avalonia .NET Core MVVM App select it and then type Avalonia.MusicStore as the Solution Name. Everything else can be left as default.Create button.Images, Icons, Fonts etc, anything that the UI might need to display,ViewModels of the project. Viewmodels should only contain UI logic. Button is enabled when the user has typed something. Open a dialog when the user clicks here, show an error if the user enters too high a number type of logic.Views of the project. Views are like HTML for native application, they describe the look and layout of your UI, but not the UI logic.INotifyPropertyChanged for more on that.)MainWindowxaml UI code that describes how the MainWindow looks and its contents.xaml file that sets up the application, it chooses the theme the UI will use and declares the ViewLocator DataTemplate.Main method where the program starts and Avalonia is configured and started.ViewLocator is a special DataTemplate. When some Data appears in the UI, it quickly looks to see if a View exists for it. This is done by naming convention. If the datas Type is MyDataViewModel then the ViewLocator will use the View named MyDataView (if it exists) in that part of the UI. This is very powerful for list based controls (ItemsControl, ListBox, etc) and ContentControl.
