Hi,

The "append_to" method is not a static method; you must use it on an
instance of GLib.File. You want to be calling "append_to" like this:

   FileOutputStream file_stream = file.append_to(FileCreateFlags.NONE,
null);

You might also notice that, compared to your old code, this call doesn't
have another parameter. Check out valadoc.org, it should help you figure out
which functions are members of the namespace vs members of classes.
