asp.net mvc - Custom ResourceProviderFactory Dependency Injection

Question

Is there anywhere in ASP.NET MVC where you can get a reference to the ResourceProviderFactory that is instantiated in order to perform Property Injection to add a custom DB Implementation to retrieve the resources from?

I have a custom resource provider being loaded but I wanted to know whether there was an alternative to using a Static DI container to inject the dependency within the Provider.

Similar to how you can inject for the Role and Membership providers in MVC.

The trick is to implement an infrastructure component calls into MVC's DependencyResolver.Current, so you can register the real ResourceProviderFactory using your favorite DI container.

Here is such a class that will do the trick:

public class MvcResourceProviderFactory : ResourceProviderFactory
{
    public override IResourceProvider CreateGlobalResourceProvider(
        string classKey)
    {
        return GetFactory().CreateGlobalResourceProvider(classKey);
    }

    public override IResourceProvider CreateLocalResourceProvider(
        string virtualPath)
    {
        return GetFactory().CreateLocalResourceProvider(virtualPath);
    }

    private static ResourceProviderFactory GetFactory()
    {
        var resolver = DependencyResolver.Current;

        var factory = resolver.GetService<ResourceProviderFactory>();

        if (factory != null)
        {
            return factory;
        }

        throw new InvalidOperationException(string.Format(
            "No {0} has been registered in the {1}.",
            typeof(ResourceProviderFactory).FullName,
            DependencyResolver.Current.GetType().FullName));
    }
}

This class can be configured as follows:

<globalization
    resourceProviderFactoryType="MyApp.MvcResourceProviderFactory, MyApp"
    enableClientBasedCulture="true" uiCulture="auto" culture="auto"
/>
