Session scoped instances in TinyIoC

Question

I need an instance of a class to be created only once per user session. How do I register such a class with TinyIoC? I'm using NancyFx.

Answer 1

I ended up writing the following code:

public static class ContainerExtensions {
    public static TinyIoCContainer.RegisterOptions SessionScoped<TRegisterType>(this TinyIoCContainer container, NancyContext context, Func<TRegisterType> factory) where TRegisterType : class
    {
        return container.Register<TRegisterType>((ctx, overloads) =>
        {
            var key = typeof(TRegisterType).FullName;
            var instance = context.Request.Session[key] as TRegisterType;
            if (instance == null) {
                instance = factory();
                context.Request.Session[key] = instance;
            }
            return instance;
        });
    }
}

I used the Nancy.Session.InProc NuGet.
