Possible causes of System.ArgumentException by StorageApplicationPermissions.MostRecentlyUsedList.GetFileAsync(String token)?

Question

Occasionally the System.ArgumentException is generated by the following statement:

storageFolderFoo = await StorageApplicationPermissions.MostRecentlyUsedList.GetFileAsync(sToken);

Message:The parameter is incorrect.

When this happens, sToken is something like {94732BC6-2729-4306-8472-83D698918E2C} which looks correct. 

Could anyone shed some light on the possible causes of this.   I know FileNotFoundException is generated if the file does not exist.

Answer 1

Likely a bug, but impossible to diagnose without a reproduction app.

If my reply answers your question, please mark this post as answered.

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

Answer 2

Thanks, Matt.  We will ignore it for now.
