Remarks

This class defines certain members (like Context, AppState, and Href(String, Object[])) that can be used in ASP.NET Web Pages as properties of the page.

All methods and properties in the HelperPage class are static, so all methods and properties that access this class must also be static.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
