Working With Shiny¶

Shiny uses the Microsoft.Extensions.DependencyInjection pattern of service registration found in ASP.NET Core applications with a Startup class. This in particular is a use case in which you will need to initialize a container prior to Forms.Init being called on the native platform. To work with Shiny you simply need to do something like the following:

// Android
[Application]
public class App : Android.App.Application
{
 public override void OnCreate()
 {
 AndroidShinyHost.Init(this, new MyStartup());
 }
}
// iOS
[Register("AppDelegate")]
public partial class AppDelegate : FormsApplicationDelegate
{
 public override bool FinishedLaunching(UIApplication app, NSDictionary options)
 {
 // this needs to be loaded before EVERYTHING
 iOSShinyHost.Init(new MyStartup());
 Forms.Init();
 this.LoadApplication(new App());
 return base.FinishedLaunching(app, options);
 }
 // if you are using jobs, you need this
 public override void PerformFetch(UIApplication application, Action<UIBackgroundFetchResult> completionHandler)
 => JobManager.OnBackgroundFetch(completionHandler);
}
