Recently I developed a metro app. In the package's installed directory, I wanna create a xml content file with the following code.

Package.Current.InstalledLocation.CreateFleAsync()

But the following exception occurred.

The call to QI for interface 'Windows.ApplicationModel.IPackageStatics' with IID '{4E534BDF-2960-4878-97A4-9624DEB72F2D}' failed with HRESULT 0x80004002 (No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))).

anyone has idea on it?

Hi,

Metro App runs in isolated sandbox. You have no write access to package's installed location.

You'd better create your xml file in app data store including local, roaming, and temporary data.

Windows.Storage.ApplicationData class can help you do it.

Please refer to http://msdn.microsoft.com/en-us/library/windows/apps/hh464917.aspx to learn more about Application Data.
