ASP.NET MVC 3, Action Filters, and Autofac Dependency Injection

Question

On ASP.NET MVC 2 I have an ActionFilterAttribute called [Transaction] that starts an NHibernate transaction before executing the a

Answer 1

Oh yuck.... Nicholas, you might need to store your ISession and Transaction in HttpContext.Items, which you should be able to get to via the ActionExecutedContext/ActionExecutingContext (perhaps setting it in the OnActionExecuting event handler), instead of keeping them in instance members. Either that, or you could call a ServiceLocator inside your filter to grab them for you (also yuck).

Now I have to go look through my MVC 3 code and see if I have any similar problems myself!

Answer 2

I just asked a similar question on google forums. Here is the link https://groups.google.com/forum/#!topic/autofac/a0qqp2b3WA8

I got the answer:

builder.RegisterType<ExtensibleActionInvoker>().As<IActionInvoker>();


builder.RegisterControllers(Assembly.GetExecutingAssembly()).InjectActionInvoker();

Then you can use property injection in your attributes.
