Answer 1

I solved the problem this way:

XAML:

WindowStyle="None"
Left="0"
Top="0"
Width="{Binding WPFSettings.Width}"
Height="{Binding WPFSettings.Height}">

Visual Basic:

Public Class WPFSettings
   Public ReadOnly Property Width() As Double
      Get
         Return System.Windows.SystemParameters.PrimaryScreenWidth
      End Get
   End Property

   Public ReadOnly Property Height() As Double
      Get
         Return System.Windows.SystemParameters.PrimaryScreenHeight
      End Get
   End Property
End Class

It works pretty good.

In my case the XAML tag of the Window had the Property SizeToContent="True" and all I had to do was to remove it.
