        xmlns:local="clr-namespace:WpfApp1" xmlns:sys="clr-namespace:System;assembly=mscorlib"
        mc:Ignorable="d" 
        Title="MainWindow" Height="450" Width="800" WindowStyle="ToolWindow" WindowStartupLocation="CenterScreen">

    <Window.Resources>
        <sys:String x:Key="myString">Hello world</sys:String>
