Using Ninject as IoC for EasyNetQ - ninject

Question

i'm using EasyNetQ library in my project and I would like to use Ninject as IoC Container for EasyNetQ components.
I created a custom logger in order to log anythong from EasyNetQ:
public class LogNothingLogger : IEasyNetQLogger
{
...
}
And then using the Ninject extension in my main function:
public class Program
{
static void Main(string[] args)
{
// Container creation and custom logger registration
IKernel cointainer = new StandardKernel();
cointainer.Bind<IEasyNetQLogger>().To<LogNothingLogger>();
// Register Ninject as IoC Container for EasyNetQ
cointainer.RegisterAsEasyNetQContainerFactory();
// Create bus
using (IBus bus = RabbitHutch.CreateBus("host=localhost"))
{
// Do something with bus...
}
}
}
But I get the following exception:
Ninject.ActivationException was unhandled
More than one matching bindings are available.
Matching bindings:
1) binding from IEasyNetQLogger to LogNothingLogger
2) binding from IEasyNetQLogger to method
Activation path:
2) Injection of dependency IEasyNetQLogger into parameter logger of constructor of type RabbitBus
1) Request for RabbitBus
Suggestions:
1) Ensure that you have defined a binding for IEasyNetQLogger only once.
[...]
Am I using this package in the wrong way? Is there any solution?
Thanks!

As the exception says, there are two bindings for IEasyNetQLogger.
I suppose that an ninject extension you are using is already binding an IEasyNetQLogger.
You could use Rebind (IBindingRoot.Rebind<IEasyNetQLogger>()) to override any existing binding for IEasyNetQLogger.
But i would also advise you to look into why the extension is already creating a binding and how it is supposed to be used.
What is the extension you are using?
Edit: i took a glance at https://github.com/mikehadlow/EasyNetQ/tree/master/Source/EasyNetQ.DI.Ninject
and i did not find any binding for IEasyNetQLogger. Are you sure you don't have defined an additional IBindingRoot.Bind<IEasyNetQLogger>().ToMethod(...) binding?
It could also be NinjectAdapter.Register<IEasyNetQLogger>(Func<IEasyNetQLogger> ...).
If you have not done so, then the EasyNetQ is already registering a logger by NinjectAdapter.Register<IEasyNetQLogger>(Func<IEasyNetQLogger> ...).
As before, you can use Rebind(..) to replace the binding (which must be done after the original binding was created!) or look into how it is supposed to work.
Of course you might also just want to skip the binding since you only created one for "log nothing logger"...
