我有两台电脑，一台在家里，一台在工作。两者都使用相同的 VS2017 Professional 版本 15.8.4，但操作系统不同：一个使用 Windows 10，另一个使用 Windows 7。在两者上，我创建了一个包含按钮的新 WPF-Project (.Net Framework 4.5)。如果我让通过Properties > Template > Convert to Local Value为特定按钮生成模板，则每台机器上的 ControlTemplates 看起来都不同。

Windows 10 模板的 XAML：

<Button.Template>
    <ControlTemplate TargetType="{x:Type Button}">
        <Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
            <ContentPresenter x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
        </Border>
        <ControlTemplate.Triggers>
            <Trigger Property="IsDefaulted" Value="True">
                <Setter Property="BorderBrush" TargetName="border" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
            </Trigger>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Background" TargetName="border" Value="#FFBEE6FD"/>
                <Setter Property="BorderBrush" TargetName="border" Value="#FF3C7FB1"/>
            </Trigger>
            <Trigger Property="IsPressed" Value="True">
                <Setter Property="Background" TargetName="border" Value="#FFC4E5F6"/>
                <Setter Property="BorderBrush" TargetName="border" Value="#FF2C628B"/>
            </Trigger>
            <Trigger Property="ToggleButton.IsChecked" Value="True">
                <Setter Property="Background" TargetName="border" Value="#FFBCDDEE"/>
                <Setter Property="BorderBrush" TargetName="border" Value="#FF245A83"/>
            </Trigger>
            <Trigger Property="IsEnabled" Value="False">
                <Setter Property="Background" TargetName="border" Value="#FFF4F4F4"/>
                <Setter Property="BorderBrush" TargetName="border" Value="#FFADB2B5"/>
                <Setter Property="Foreground" Value="#FF838383"/>
            </Trigger>
        </ControlTemplate.Triggers>
    </ControlTemplate>
</Button.Template>

Windows 7 模板的 XAML：

<Button.Template>
    <ControlTemplate TargetType="{x:Type Button}">
        <Themes:ButtonChrome x:Name="Chrome" BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderPressed="{TemplateBinding IsPressed}" RenderDefaulted="{TemplateBinding IsDefaulted}" SnapsToDevicePixels="True">
            <ContentPresenter ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
        </Themes:ButtonChrome>
        <ControlTemplate.Triggers>
            <Trigger Property="IsKeyboardFocused" Value="True">
                <Setter Property="RenderDefaulted" TargetName="Chrome" Value="True"/>
            </Trigger>
            <Trigger Property="ToggleButton.IsChecked" Value="True">
                <Setter Property="RenderPressed" TargetName="Chrome" Value="True"/>
            </Trigger>
            <Trigger Property="IsEnabled" Value="False">
                <Setter Property="Foreground" Value="#FFADADAD"/>
            </Trigger>
        </ControlTemplate.Triggers>
    </ControlTemplate>
</Button.Template>

在 Windows 7 上，它还添加了一个新的命名空间：

xmlns:Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero"

问题是，在 Windows 7 上生成的代码有问题：

The name "ButtonChrome" does not exist in the namespace "clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero"

如何防止在 Windows 7 上生成错误模板？
