Remarks

The HttpApplicationStateWrapper class derives from the HttpApplicationStateBase class and serves as a wrapper for the HttpApplicationState class. This class exposes the functionality of the HttpApplicationState class while also exposing the HttpApplicationStateBase type. The HttpApplicationStateBase class enables you to replace the original implementation of the HttpApplicationState class in your application with a custom implementation, such as when you perform unit testing outside the ASP.NET pipeline.
