Registering an implementation that supports more than one interface

[MartinRobins]

I have an interface that is inherited from another...

public interface ICommonSettingsProvider {...}

public interface ISpecificSettingsProvider : ICommonSettingsProvider {...}

I then have an implementation...

public class SpecificSettingsProvider : ISpecificSettingsProvider {...}

Currently, I find that I have to register both interfaces in the container...

containerRegistry.RegisterSingleton<ISpecificSettingsProvider, SpecificSettingsProvider>();

ISpecificSettingsProvider specificSettingsProvider = ContainerLocator.Container.Resolve<SpecificSettingsProvider>();
containerRegistry.RegisterInstance<ICommonSettingsProvider>(specificSettingsProvider);
containerRegistry.RegisterInstance<ISpecificSettingsProvider>(specificSettingsProvider);

Is it possible for me to register this instance (or even just register as a singleton) the implementation for both interfaces at the same time or is this the best way to do it?

Thanks.

I think dryioc supports this with RegisterMany.

@thomasgalliker That looks like the answer I was looking for, and it is supported by the Prism IContainerRegistry too. The single line...

containerRegistry.RegisterManySingleton<SpecificSettingsProvider>(typeof(ICommonSettingsProvider), typeof(ISpecificSettingsProvider));

... replaces all 4 of my original lines above.

Thanks,
