Generally a class in the library shouldn't be reading web.config directly and take settings in constructor.

However it is acceptable for library in some scenarios to read the web.config directly. For that you can define a custom configuration section or use WebConfigurationManager.AppSettings

You need to add reference to System.Web assembly and you need to include the namespace System.Web.Configuration in the file where you want to use configuration manager.
