Host configuration is used for the properties of the IHostEnvironment implementation. Web apps implement the IWebHostEnvironment interface, which inherits IHostEnvironment and adds the WebRootPath. Inject the IHostEnvironment service into a class to get information about the following settings:

Unblocks extensions such as RunAsync and WaitForShutdownAsync.

Listens for Ctrl+ C/SIGINT (Windows), ⌘+ C (macOS), or SIGTERM and calls StopApplication to start the shutdown process.

ConsoleLifetime is the default IHostLifetime implementation. The last implementation registered is used. The IHostLifetime implementation controls when the host starts and when it stops. Public Task StopAsync(CancellationToken cancellationToken)

Public Task StartAsync(CancellationToken cancellationToken) => _hostApplicationLifetime = hostApplicationLifetime IHostApplicationLifetime hostApplicationLifetime) Public HostApplicationLifetimeEventsHostedService( Private readonly IHostApplicationLifetime _hostApplicationLifetime The following example is an IHostedService implementation that registers IHostApplicationLifetime event handlers: public class HostApplicationLifetimeEventsHostedService : IHostedService

Triggers the ApplicationStopped event handlers, which allows the app to run logic after the application has shutdown.

The server sends the connection close header for further requests on existing connections. The server waits for requests on existing connections to complete, for as long as the shutdown timeout allows.

Stops the server, which disables new connections.

Triggers the ApplicationStopping event handlers, which allows the app to run logic before the shutdown process begins.

When performing a graceful shutdown, the host: The interface also includes a StopApplication method, which allows apps to request a graceful shutdown. Three properties on the interface are cancellation tokens used to register app start and app stop event handler methods. Inject the IHostApplicationLifetime (formerly IApplicationLifetime) service into any class to handle post-startup and graceful shutdown tasks. The following services are registered automatically:įor more information on framework-provided services, see Dependency injection in ASP.NET Core.

For the IIS default options, see Host ASP.NET Core on Windows with IIS.

Adds Forwarded Headers middleware if ASPNETCORE_FORWARDEDHEADERS_ENABLED equals true.

For the Kestrel server's default options, see Configure options for the ASP.NET Core Kestrel web server.

Sets Kestrel server as the web server and configures it using the app's hosting configuration providers.

Loads host configuration from environment variables prefixed with ASPNETCORE_.

Enables scope validation and dependency validation when the environment is Development.

EventLog (only when running on Windows).

User secrets when the app runs in the Development environment.

Environment variables prefixed with DOTNET_.

Sets the content root to the path returned by GetCurrentDirectory.

The following code creates a host with an IHostedService implementation added to the DI container: await Host.CreateDefaultBuilder(args)įor an HTTP workload, call ConfigureWebHostDefaults after CreateDefaultBuilder: await Host.CreateDefaultBuilder(args) The host is typically configured, built, and run by code in the Program.cs.

Including all of the app's interdependent resources in one object enables control over app startup and graceful shutdown. In a web app, one of the IHostedService implementations is a web service that starts an HTTP server implementation. When a host starts, it calls IHostedService.StartAsync on each implementation of IHostedService registered in the service container's collection of hosted services. Host definitionĪ host is an object that encapsulates an app's resources, such as: For more information on WebApplicationBuilder and WebApplication, see Migrate from ASP.NET Core 5.0 to 6.0.įor information on using the. The ASP.NET Core templates create a WebApplicationBuilder and WebApplication, which provide a streamlined way to configure and run web applications without a Startup class. This article provides information on using the.
