As far as I can remember (It is more than 4 years ago), you can create a style to use with a WPF window.
据我所知（已经超过 4 年了），您可以创建与 WPF 窗口一起使用的样式。
This is a sample window Style:
这是一个示例窗口样式：

<Setter Property="Foreground"
Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Window}">
<Grid>
<Border x:Name="MainBorder"
BorderBrush="{DynamicResource MainWindowBorderBrush}"
BorderThickness="1"
CornerRadius="2"
Background="{DynamicResource MainWindowBackgroundBrush}">
<DockPanel LastChildFill="True">
<Rectangle x:Name="PART_LEFT_BORDER"
Width="2"
Cursor="SizeWE">
<Rectangle.Fill>
<SolidColorBrush Color="Transparent" />
</Rectangle.Fill>
</Rectangle>
<Rectangle x:Name="PART_RIGHT_BORDER"
Cursor="SizeWE"

DockPanel.Dock="Right">

<Rectangle x:Name="PART_BOTTOM_BORDER"
Cursor="SizeNS"
Height="2"
DockPanel.Dock="Bottom">
<Rectangle.Fill>
<SolidColorBrush Color="Transparent" />
</Rectangle.Fill>
</Rectangle>
<Border x:Name="PART_TITLEBAR"
Margin="2,0,2,2"
Height="40"
DockPanel.Dock="Top"
CornerRadius="2"
Background="Transparent">
<DockPanel LastChildFill="False">
<TextBlock Margin="8,0,0,4"
VerticalAlignment="Center"
FontStretch="UltraExpanded"
Foreground="Black"
TextTrimming="CharacterEllipsis"
TextWrapping="NoWrap"
Text="{TemplateBinding Title}"
FontSize="16" />
<Button x:Name="PART_CLOSE"
DockPanel.Dock="Right"
Style="{DynamicResource FlatButton}"
VerticalAlignment="Center"
Margin="0,0,4,0">
<Image Source="/MixModes.Synergy.Resources;
component/Resources/Close.png"
Stretch="None"
Margin="4" />
</Button>
<Button x:Name="PART_MAXIMIZE_RESTORE"
DockPanel.Dock="Right"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Style="{DynamicResource FlatButton}">
<Image x:Name="MaximizeRestoreImage"
Source="/MixModes.Synergy.Resources;
component/Resources/Restore.png"
Stretch="None"
Margin="4" />
</Button>
<Button x:Name="PART_MINIMIZE"
HorizontalAlignment="Center"
Style="{DynamicResource FlatButton}"
VerticalAlignment="Center"
DockPanel.Dock="Right">
<Image Margin="4"
Source="/MixModes.Synergy.
Resources;component/Resources/
Minimize.png"
Stretch="None" />
</Button>
</DockPanel>
</Border>
<!-- Title bar separator-->
<Border Height="1"
DockPanel.Dock="Top"
Background="{DynamicResource
MainWindowTitleBarSeparator}" />
<!-- Actual Window Content -->
<AdornerDecorator DockPanel.Dock="Bottom">
<ContentPresenter />
</AdornerDecorator>
</DockPanel>
</Border>
</Grid>
<ControlTemplate.Triggers>
<DataTrigger Binding="{Binding RelativeSource=
{RelativeSource Self}, Path=Maximized}"
Value="False">
<Setter TargetName="MaximizeRestoreImage"
Property="Source"
Value="/MixModes.Synergy.Resources;
component/Resources/Maximize.png" />
</DataTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
And the result will look like this:
结果将如下所示：

You can use the XAML below to achieve rounded corner windows in WPF, the problem with this approach is you'll have to implement your own buttons for Minimize,Maximize and Close.
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。
Fortunately there is a library on code plexwhich does all this for you
幸运的是，code plex上有一个库可以为您完成所有这些工作
<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>
