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. |
