A new System.Windows.Forms.AccessibleObject for the control.
If you do not explicitly call the MenuStrip.CreateAccessibilityInstance method, it will be called when the Control.AccessibilityObject property is referenced.
To get or set the Control.AccessibilityObject property, you must add a reference to the Accessibility assembly installed with the .NET Framework.
For a code example of using MenuStrip.CreateAccessibilityInstance, see Control.CreateAccessibilityInstance.
