Example:

1. I have a class AppSettings with property public string[] SomeValues { get; set; }.
2. My appsettings.json is {"SomeValues": []}.

When I bind an instance of AppSettings to the configuration like this: configurationBuilder.AddJsonFile("appsettings.json").Build().Bind(appSettings), property SomeValues is null. I expect empty array.

Note that if I change appsettings.json to {"SomeValues": ["val1", "val2"]}, SomeValues does get set to the expected string array. So generally binding is working.
