ApplicationData.ClearAsync() doesn't work in Windows 8.1 Universal App


I'm trying to clear the application data when user logout of the application & I found ApplicationData.ClearAsync() which fits my requirement which is similar to IsolatedStorageSettings.ApplicationSettings.Clear() but it gives me an below error

An exception of type 'System.IO.FileLoadException' occurred in but was not handled in user code

Additional information: The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020)

I'm not able to understand this as there is no file that I have opened or using as I'm simply using as isolatedstorage just in key value pair.

Kindly help me figure out how I can solve this issue. Thanks in advance

It may fail if you have images used in your xaml for instance : is it the case ? One solution I ended up was to clear ApplicationData on the next launch.

You could also list the files and try to delete them one by one.
