Disable implicit binding/injection of non explicitly bound classes in Ninject 2+

Question

If you request an unbound object from NInject, then the default behaviour is (if a suitable constructor is available) appears to be to create an instance of the appropriate object.

I'd like to disable this behaviour (I had a difficult to debug issue because something was auto-bound instead of picking up my custom binding in a module). This question hints that it is possible, but I'm unable to find the answer from the NInject wiki.

Answer 1

Remove the SelfBindingResolver from the kernel components after creation:

kernel.Components.RemoveAll<IMissingBindingResolver>();
kernel.Components.Add<IMissingBindingResolver, DefaultValueBindingResolver>();

Answer 2

The following is a better, more direct way of removing the SelfBindingResolver, without assuming that the DefaultValueBindingResolver is the only other IMissingBindingResolver component:

kernel.Components.Remove<IMissingBindingResolver, SelfBindingResolver>();

It's possible the Remove<T, TImplementation>() method was only added in a recent version of Ninject, but this works for me using Ninject 3.2.2.0.
