Ninject Binding "all inheriting from x"

Question

Pretty usual scenario:

public class A { }
public class B:A {}
public class C:A {}

I really wonder if it is possible to create Ninject Bindings that resolve all inheriting from A like the following:

Bind<A>().ToMethod(ctx => proxyFactory.CreateProxy(ctx.Request.Service) as A);

This of course only works for Requests on type A. Requests for B and C are handled the default way.

Thanks in advance

Why don't you bind `B` and `C` to `A` and call `GetAll()` or take `IEnumerable ` in the constructor? — khellang, Nov 22 '12 at 15:05
In my application A is a ViewModelBase class. Whenever I add new ViewModels, I'd prefer not to have to update the mappings again... — Sebastian Edelmeier, Nov 23 '12 at 07:44

If it's a possibility to add ninject.extensions.conventions, you can bind them dynamically like this:

kernel.Bind(x => x
    .FromThisAssembly()
    .SelectAllClasses()
    .InheritedFrom<A>()
    .BindBase()
    .Configure(c => c.InTransientScope()));
