The reason it's not supported is because the Stream you're using wraps a java.io.InputStream, and the InputStream class doesn't expose any equivalent to the Length property:

	http://androidapi.xamarin.com/?link=T%3aJava.IO.InputStream%2f*

Now, why are you using BinaryReader.ReadBytes(s.Length)? What you can instead do is read + copy the stream into a MemoryStream:

	var dest = new MemoryStream();
	using (var s = Assets.Open ("model.dds"))
		s.CopyTo (dest);
	byte[] data = dest.ToArray ();
