Remarks

For more information about the Deferral class, see the section about deferrals in App lifecycle and the ExtendedExecution sample.

Javascript apps should not allow navigation before completing a DeferralCompletedHandler. Doing so could cause an app to crash and should be considered a programming error.

Constructors

Deferral(DeferralCompletedHandler)
