       <para>The <see cref="T:Microsoft.Maui.Controls.Application" /> class is the core of a .NET MAUI application. It sets the root page of the application, and provides events to respond to pushing and popping of modal views. Visual Studio creates this class for the developer in the appropriate project in a new .NET MAUI solution.</para>
