How to set background color window to RGB color

[Sylvain]

I'm making a WPF application in VS2010. I'm trying to set the background color of the form to a specific color expressed in RGB. However, when I debug, i get a black form. The copypasted code:

Public Class Window1

Private Sub Window1_Loaded( ByVal sender As Object, ByVal e As System.Windows. RoutedEventArgs ) Handles Me.Loaded

Dim clrColor As New System.Windows. Media.Color

clrColor.R = 20
clrColor.G = 50
clrColor.B = 100

Dim s As New SolidColorBrush

s.Color = clrColor

Me.Background = s
End Sub
End Class
