ASP.NET lifetime provider doesn't dispose

[Daniel15]

Unless I'm missing something, it looks like the ASP.NET lifetime provider does not dispose registered components at the end of a request. All registered components that are IDisposable should be disposed at the end of the request.

Here's how I fixed it on mine:

1 - Add code to dispose all created objects in the HTTP context. I just stuck this in TinyIoCAspNetExtensions:

private const string PREFIX = "TinyIoC.HttpContext.";
...
public static void DisposeAll()
{
    var items = HttpContext.Current.Items;
    var disposableItems = items.Keys.OfType<string>()
        .Where(key => key.StartsWith(PREFIX))
        .Select(key => items[key])
        .Where(item => item is IDisposable);

    foreach (var item in disposableItems)
    {
        ((IDisposable)item).Dispose();
    }
}

2 - Call it at the end of the request. My init code is in WebActivator but you could just stick it in Application_EndRequest in Global.asax.cs:

using System;
using System.Web;
using Microsoft.Web.Infrastructure.DynamicModuleHelper;
using TinyIoC;

[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(MyApp.Initializer), "Initialize")]

namespace MyApp
{
    internal static class Initializer
    {
        public static void Initialize()
        {
            InitializeIoC();
            DynamicModuleUtility.RegisterModule(typeof(IocPerRequestDisposal));
        }

        internal class IocPerRequestDisposal : IHttpModule
        {
            public void Init(HttpApplication context)
            {
                context.EndRequest += (sender, args) => HttpContextLifetimeProvider.DisposeAll();
            }
            public void Dispose() { }
        }
    }
}
