Castle.Windsor lifestyle depending on context?

Question

I have a web application where many components are registered using .LifestylePerWebRequest(), now I've decided to implement Quartz.NET, a .NET job scheduling library, which executes in separate threads, and not the Request thread.

As such, HttpContext.Current yields null. My services, repositories, and IDbConnection were instanced so far using .LifestylePerWebRequest() because it made it easier to dispose of them when the requests ended.

Now I want to use these components in both scenarios, during web requests I want them to remain unaffected, and in non-request contexts I want them to use a different Lifestyle, I figure I can handle the disposing myself, but how should I go about it for choosing a lifestyle for the components based on the current context?

Currently I register services (for example), like this:

container.Register(
    AllTypes
        .FromAssemblyContaining<EmailService>()
        .Where(t => t.Name.EndsWith("Service"))
        .WithService.Select(IoC.SelectByInterfaceConvention)
        .LifestylePerWebRequest()
);

I figure I should be using some kind of extension method but I just don't see it..

You should use Hybrid Lifestyle from castleprojectcontrib.

An hybrid lifestyle is one that actually blends two underlying lifestyles: a main lifestyle and a secondary lifestyle. The hybrid lifestyle first tries to use the main lifestyle; if it's unavailable for some reason, it uses the secondary lifestyle. This is commonly used with PerWebRequest as the main lifestyle: if the HTTP context is available, it's used as the scope for the component instance; otherwise the secondary lifestyle is used.
