Description
Fully open source version of Prism including MVVM, dependency injection, commands, EventAggregator, and others.
Prism 8 supports WPF, Xamarin Forms and UNO, but not Silverlight, Windows 8/8.1/WP8.1 or UWP.
Getting Started
- Nuget packages
- Prism.Core
- Prism.Wpf
- Prism.DryIoc
- Prism Template Pack Visual Studio extension
Dependency Injection
| App.xaml.cs |
public partial class App
{
protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
// register a singleton service
containerRegistry.RegisterSingleton<IMyService, MyService>();
// registera transient service
containerRegistry.Register<IMyService, MyService>();
}
|
- singleton service: for a service which is used throughout the application and that retains its state.
- transient service: create a new instance each time.
- scoped service: no implementation because unlike a web application, desktop applications are dealing with a single user and not scoped user requests.
