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.

.NET Framework

Supported in: 4, 3.5 SP1

Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2

The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
