据我所知（超过4年前），您可以创建一个用于WPF窗口的样式。

这是示例窗口样式：

                      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> 
    <Style x:Key="MainWindow" 
           TargetType="{x:Type Window}"> 
        <Setter Property="Foreground" 
                Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}" /> 
        <Setter Property="Template"> 
            <Setter.Value> 
                <ControlTemplate TargetType="{x:Type Window}">

                                Background="{DynamicResource MainWindowBackgroundBrush}">

您可以使用下面的XAML在WPF中实现圆角窗口，这种方法的问题是您必须实现自己的最小化，最大化和关闭按钮。

幸运的是code plex上有一个图书馆可以为您完成所有这些

<Window x:Class="WpfApplication2.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    AllowsTransparency="True"
    WindowStyle="None"
    Padding="0"
    WindowStartupLocation="CenterScreen" Height="200" Width="200" >
    <Border BorderBrush="Blue" BorderThickness="2" CornerRadius="6" >
    </Border>
</Window>
