Using Autofac in ASP.NET along with the ContainerDisposalModule, how can i support fire and forget calls that have component dependencies that need to be resolved? The problem I’m running into is that the ASP.NET request completes and disposes the lifetime scope of the request before the Task is ran, so any components that need to be resolved in the new thread fail with the message “Instances cannot be resolved and nested lifetimes cannot be created from this LifetimeScope as it has already been disposed”. What’s the best way to support fire and forget call using Autofac in ASP.NET? I don’t want to delay the request to perform certain tasks which can be done on background threads.

    You need to create a new lifetime scope that is independent of the request lifetime scope. The blog post below shows an example of how to do this using MVC but the same concept can be applied to WebForms.

    If you need to ensure that the async work is definitely performed after the request is finished then this is not a good approach. In such cases I would recommend posting a message onto a queue during the request allowing a separate process to pick it up and perform the work.
