My apologies - there are a few properties that we allow you to configure like TileMode and Stretch. We just have not enabled all the properties of a TileBrush in v1. You should still be able to create and apply a TileBrush (for example, ImageBrush or VisualBrush) in Blend. You just cannot control it with the precision you can do in WPF. Thanks, -Unni
