System 2.0.0.0 4.0.0.0 System.Collections.Hashtable The class is the base class used by applications to provide contextual information to the settings provider. Although the class is not abstract, an application can choose to create a specialized class that inherits from class and provides additional information to specific types of providers. The provider can then examine contextual settings when writing properties. The primary purpose of the class is to provide features that use the class and related infrastructure. The class provides additional feature-specific contextual information about the property data being stored by the instance. Therefore, it is very simple to store additional information in a class without deriving from it (or from other Settings* classes) in order to support additional feature-specific context information. For example, ASP.NET uses the class to pass along the username associated with the data managed by a instance, as well as a property indicating whether the user is considered authenticated. In this way, ASP.NET uses the class to identify authenticated versus anonymous Profile data. Provides contextual information that the provider can use when persisting settings.
