    It's very easy. No matter how many constructor arguments, the binding stays the same:

    Bind().To();
    

    Let's say MyAuthenticator had a constructor with one parameter of type IFoo. All you got to do is tell ninject how it can resolve/create an IFoo. Again, very simple:

    Bind().To();
    

    You don't need WithConstructorArgument ever, except in case you want to override the default behavior of ninject. Let's say MyAuthenticator has a parameter of type IFoo plus another parameter string seed which you want to configure specifically. All you'd need is:

    Bind().To();
    Bind().To()
        .WithConstructorArgument("seed", "initialSeedValue");
    

    no need to specify the value of the IFoo parameter!
