Trying to inject a dependency on an action filter in MVC with autofac the other day, property injection seems to be the order of the day. So here's how to do it:
Here's the filter :
public class MyFilter: FilterAttribute, IAuthorizationFilter
{
public Dependency MyDependency { get;set;}
}
Autofac registrations:
var builder = new ContainerBuilder();
builder.RegisterFilterProvider();
builder.Register<Dependency>(c => new MyConcreteDependency());
builder.RegisterType<MyFilter>().PropertiesAutowired();
note the RegisterFilterProvider line very important.....
