Dim myViewbox As New Viewbox()
myViewbox.StretchDirection = StretchDirection.Both
myViewbox.Stretch = Stretch.Fill
myViewbox.MaxWidth = 400
myViewbox.MaxHeight = 400

Visual C++
// Create a Viewbox and add it to the Canvas
myViewbox = gcnew Viewbox();
myViewbox->StretchDirection = StretchDirection::Both;
myViewbox->Stretch = Stretch::Fill;
myViewbox->MaxWidth = 400;
myViewbox->MaxHeight = 400;

C#

myViewbox = new Viewbox();
