Splat.Ninject is an adapter for IMutableDependencyResolver. It allows you to register your application dependencies in a Ninject IKernel. You can then use the container as Splat's internal dependency resolver.
var kernel = new StandardKernel();
kernel.Bind<IViewFor<MainViewModel>>().To<MainPage>();
kernel.Bind<IViewFor<SecondaryViewModel>>().To<SecondaryPage>();
kernel.Bind<MainViewModel>().ToSelf();
kernel.Bind<SecondaryViewModel>().ToSelf();container.UseNinjectDependencyResolver();Now, when registering or resolving services using AppLocator.Current, or via ReactiveUI, they will be directed to the Ninject DI container.
