Memory leak in Owin.AppBuilderExtensions

Question

I use OWIN + Microsoft.AspNet.Identity.Owin (v.2.0.0.0) in Web application. I register UserManager/DbContext per web request, as widely recommended:

app.Crea

You can put the logic for disposing the instances you create with CreatePeOwinContext() in the same callback you use to create this intances. That is:

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        app.CreatePerOwinContext(ClassIWantOneInstancePerContext.Create);

        //other code...
    }
}

Then you only should care about to include a call to DisposeOnPipelineCompleted() within the callback used to instantiate your class. That is:

public class ClassIWantOneInstancePerContext
{
     //other code...

    public static ClassIWantOneInstancePerContext Create()
    {
        ClassIWantOneInstancePerContext TheInstance = new ClassIWantOneInstancePerContext();
        HttpContext.Current.DisposeOnPipelineCompleted(TheInstance);

        return TheInstance;
    }
}

Also don't forget to include the Dispose() method on your class definition!
