Question

I have a ViewModelLocator from MVVMLight containing my MainViewModel.

I have another singleton class ResourceLogger which does something else.

ResourceLogger is created in App.xaml.cs using:

var resourceLogger = kernel.Get<ResourceLogger>();

MainViewModel depends on ResourceLogger.

I am having problems injecting ResourceLogger into the MainViewModel as follows:

[Inject]
public MainViewModel(ResourceLogger resourceLogger) { ... }

The problem is that it creates two ResourceLogger classes.

The NinjectModule looks as follows:

Bind<ResourceLogger>().ToSelf().InSingletonScope();
Bind<MainViewModel>().ToSelf().InSingletonScope();

Is there some way to share the kernel between App.xaml.cs and ViewModelLocator?

How can I resolve this problem?

Answer 1

Easiest way would be to have create public static class/variable for the kernel, then use it for all registration and calls to Get().

As an aside, you should do what you can to only have one call to kernel.Get() (or at least as few calls as possible) in your whole system.
