Setting Windows 8 account picture with .NET/WinRT hybrid

[chris128]

I'm having the exact same problem. Everything about using "Windows Runtime" methods from regular .NET apps has been incredibly frustrating and troublesome so far. I'm doing it slightly differently to you but still getting the same problem (i.e. no exception thrown but the returned value is just "Failure"). I've also verified that the Windows.System.UserProfile.UserInformation.AccountPictureChangeEnabled property is True - it was initially False but then I went into control panel or whatever the hell it is called on Windows 8 now and set the "Let apps use my name and account picture" option to On (stupid how that setting implies apps will only be able to view it not change it, but the AccountPictureChangedEnabled property implies apps are now allowed to change it as well).

Here's how I'm doing it, in case anyone can spot any problems:
