UnauthorizedAccessException during storageFolder.CreateFileAsync

Question

I have the following piece of code

    // Point to c:\\users\\yancheng\\documents\\visual studio 2012\\Projects\\App5\\App5\\bin\\x86\\Debug\\AppX
    StorageFol

From your comments above, I'm assuming that you've checked the "Documents Library" capability in the package.appxmanifest.

Check out the remarks in the documentation for StorageFolder.CreateFileAsync. It says: "If you try to create a file in a virtual folder like a library or a file group, this method may fail." Then in the Example section, it shows a different way to create a new file in the Documents library using Windows.Storage.KnownFolders.documentsLibrary.createFileAsync(). Can you try that and see if it works?
