Is there Application_End from Global.asax in Owin?
AppProperties, found in Microsoft.Owin.BuilderProperties, exposes the CancellationToken for OnAppDisposing.
You can get this token and register a callback to it
public class Startup{ public void Configuration(IAppBuilder app) { var properties = new AppProperties(app.Properties); CancellationToken token = properties.OnAppDisposing; if (token != CancellationToken.None) { token.Register(() => { // do stuff }); } }}
I packaged this up in a little helper so you can do this:
public class Startup{ public void Configuration(IAppBuilder app) { app.OnDisposing(() => { // do stuff }); }}The helper:
static class AppBuilderExtensions{ public static void OnDisposing(this IAppBuilder app, Action cleanup) { var properties = new AppProperties(app.Properties); var token = properties.OnAppDisposing; if (token != CancellationToken.None) { token.Register(cleanup); } }}
