我使用了大的答案从NathanAW创造了ResourceDictionary含有Window一个Style（应由MainWindow使用），包含在关键件来解决这个问题。
更新：为ToolBar增加支持以及Menu
它包括命中测试专门为MainMenu的栏或工具栏，以决定是否重点应该被允许。
我之所以使用ResourceDictionary的理由是为了重复使用，因为我们将在很多项目中使用它。此外，MainWindow背后的代码可以保持清洁。
MainWindow可以使用这个风格
<Window...>
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="NoFocusMenuWindowDictionary.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Window.Resources>
<Window.Style>
<StaticResource ResourceKey="NoFocusMenuWindow"/>
</Window.Style>
<!--...-->

感谢您的链接，我实际上已经阅读了三次。虽然不能真正使用这些属性来工作，但是，他们看起来好像是为了解决像这样的问题。有什么想法如何工作？:) –
Meleak，我添加了一些信息，我发现通过使用Spy ++来观看VS发送的Windows消息。通过将此代码添加到主窗口，我能够使一个简单的测试应用程序的行为与VS类似。主窗口有一个菜单控件，并且还打开了一个子窗口。通过上面的代码，点击菜单时，子窗口不会松动焦点。 – NathanAW
我已经创建了一个显示这个工作的示例。有几个比上面提到的更少的细节。这些在示例的代码注释中进行了描述。 – NathanAW
