wpf在Windows 7上提供的焦点视觉提示是一条虚线，如下所示：

Now, how can I change the way it looks? How can I control its appearence?

Try something like following

尝试以下内容

<Window x:Class="FocusVisualStyle.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
<Window.Resources>
    <Style x:Key="MyFocusVisualStyle">
        <Setter Property="Control.Template">
            <Setter.Value>
                <ControlTemplate>
                    <Rectangle Margin="-2" StrokeThickness="1" Stroke="Red"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>
<StackPanel Orientation="Horizontal" Height="24">
    <TextBox Width="96"/>
    <Button Content="Yes" Width="64" FocusVisualStyle="{DynamicResource MyFocusVisualStyle}"/>
    <Button Content="No" Width="64" FocusVisualStyle="{DynamicResource MyFocusVisualStyle}"/>
</StackPanel>

You can customise to suit your liking. This is just a starting point.

您可以根据自己的喜好进行自定义。这只是一个起点。

Edit: Since so many people have liked this solution here is another example which changes focus visual style for all buttons and textboxes without explicit setting of FocusVisualStyle property for each control (see that DynamicResource thingy?) in xaml

编辑：由于这么多人喜欢这个解决方案，这里是另一个改变所有按钮和文本框的焦点视觉风格的例子，而没有为xaml中的每个控件（参见DynamicResource thingy？）显式设置FocusVisualStyle属性

Also it uses animation to change the colour of the focus rectangle.

它还使用动画来改变焦点矩形的颜色。

Enjoy :)

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
<Window.Resources>
    <Style x:Key="MyFocusVisualStyle">
        <Setter Property="Control.Template">
            <Setter.Value>

                    <Rectangle Margin="-2" StrokeThickness="2" RadiusX="2" RadiusY="2" >

                            <SolidColorBrush Color="Red" x:Name="RectangleStroke" />
                        </Rectangle.Stroke>
                        <Rectangle.Triggers>
                            <EventTrigger RoutedEvent="Rectangle.Loaded" >

                                    <Storyboard>
                                        <ColorAnimation From="Red"
                                                        To="Orange"
                                                        Duration="0:0:0.5" 
                                                        RepeatBehavior="Forever" 
                                                        Storyboard.TargetName="RectangleStroke"
                                                        Storyboard.TargetProperty="Color"/>
                                        <DoubleAnimation To="3" 
                                                         Duration="0:0:0.5"
                                                         RepeatBehavior="Forever"
                                                         Storyboard.TargetProperty="StrokeDashOffset" />
                                    </Storyboard>
                                </BeginStoryboard>
                            </EventTrigger>
                        </Rectangle.Triggers>
                    </Rectangle>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

    <Style TargetType="{x:Type Button}">
        <Setter Property="FocusVisualStyle" Value="{StaticResource MyFocusVisualStyle}" />
    </Style>
    <Style TargetType="{x:Type TextBox}">
        <Setter Property="FocusVisualStyle" Value="{StaticResource MyFocusVisualStyle}" />
    </Style>
</Window.Resources>
<StackPanel Orientation="Horizontal" Height="24">
    <TextBox Width="96"/>
    <Button Content="Yes" Width="64" />
    <Button Content="No" Width="64" />
</StackPanel>

Here you see that I have styles for Button and TextBox which set the property FocusVisualStyle for all the buttons and text boxes in this window.

在这里你看到我有Button和TextBox的样式，它为这个窗口中的所有按钮和文本框设置了属性FocusVisualStyle。
