Description

By having a JSON element in appSettings, disregarding the environment. It seems that the binder can't map the "ContentSecurityPolicy" children elements:

"ContentSecurityPolicy": {
    "DefaultSrc": [],
    "ScriptSrc": [],
    "FrameAncestors": [],
    "PluginTypes": [],
    "ReportTo": [],
    "NavigateTo": []
  }

E.g:

IConfiguration configuration = ... ;
IConfigurationSection cspSection = _configuration?.GetSection("ContentSecurityPolicy");
Assert.IsFalse(cspSection.GetChildren().Any()); //passed

Other information

Is this somehow related with this closed issue?
