The problem is in your XAML, in the Icon property. You can try simply using

Icon="Client.ico"

instead of the absolute path

Icon="/Client;component/Client.ico"

You' probably want to set up a single icon for your whole application instead of an icon per window. See the MSDN reference on System.Windows.Window.Icon for more information.
