Remarks

Only one instance of the ApplicationManager object is created by an ASP.NET host process in the default application domain. If an instance of the ApplicationManager class is not available, the GetApplicationManager method first creates an instance of the ApplicationManager class and then returns the newly created object. If an instance of the ApplicationManager class was previously created, the GetApplicationManager method returns the existing object.
