Title Body

The challenge I am facing with Ninject currently is that when I use Rebind<>() it removes all bindings, even those that are conditional. Let me give you a silly example below. Basically what I find undesired behaviour in my case is that when Rebind is called it will remove the conditional WhenInjectedInto<T> binding instead of just overwriting the non-conditional Bind<T> . In the sample below the contract Contract.Assert(cat is Wild); in the ctor will fail after the Rebind. Is there a way to do what I want - being the ability to keep already injected conditional bindings and overwrite only the non-conditional one? P.S: In reality I am trying to do some interesting things with DataContext scopes depending on where they are injected (in a request or in an async command) void Main() { StandardKernel kernel = new StandardKernel(); kernel.Bind<ICat>().To<Wild>(); kernel.Bind<ICat>().To<Wild>() .WhenInjectedInto<EvilCat>(); kernel.Rebind<ICat>().To<Domestic>(); Contract.Assert(kernel.Get<ICat>() is Domestic); kernel.Get<EvilCat>(); } interface ICat {} class Domestic : ICat {} class Wild : ICat { } class EvilCat { public EvilCat(ICat cat) { Contract.Assert(cat is Wild); } }
