Gets or sets the time at which the action’s schedule expires.
Assembly: Microsoft.Phone (in Microsoft.Phone.dll)
The action will not be invoked after the expiration time has been reached. The action is scheduled to trigger based on the BeginTime property. However, if this time is missed, for example, if the phone was turned off, the expiration time will prevent the action from displaying. The time value should be in the device’s local time.
