ApplicationView.GetForCurrentView() occasionally throws "The service is already registered"

Hong 1,526

ApplicationView avCurrent = ApplicationView.GetForCurrentView();

The above code occasionally throws the following exception:

System.Exception: The service is already registered.

The service is already registered.

Stack Trace:
at System.Runtime.InteropServices.McgMarshal.ThrowOnExternalCallFailed(Int32, RuntimeTypeHandle) + 0x21
at __Interop.ComCallHelpers.Call(__ComObject, RuntimeTypeHandle, Int32, Void*) + 0xbe
at __Interop.ForwardComStubs.Stub_3TThis, TResult + 0x37
at Windows.UI.ViewManagement.ApplicationView.GetForCurrentView() + 0x2c

It is rare. I am curious about the possible cause.

In which scenario will this behavior happen? Could you reproduce this? It is hard to find out why it happens without more details. I'd suggest you use App Center in your app to see if you could get more detail information.
