      h.height = 1.9
      Console.Out.WriteLine("The height is {0} ", h.height)
   End Sub
End Module

You construct a new Horse object and then you set its height to 1.9, and you output the value of the height property to the console. The second line in Sub Main (h.height = 1.9) will call the property procedure and execute its Set block. The Value implicit variable will be set to 1.9. That means it would pass verification using the If statement and will set the m_height field value to be 1.9.

Next you read the value (execute ...
