我遇到错误命名空间中名称metroWindow不存在：MahApps.Metro.Controls; assembly = MahApps.Metro＆＃34;我不知道问题出在哪里我也检查了由NuGet取代的mahapps，但仍然是同样的问题，我目前正在使用VS2012。我已经检查过几个堆栈问题，但问题仍然存在。

就我而言，随着MahApps nuget的基本安装，它得以实现。所以，代码不是问题。尝试卸载MapApps nuget，然后重新安装或在程序包管理器控制台中运行以下命令：
Install-Package MahApps.Metro -Version 1.3.0
请记住，不是您的代码，而是您的配置。如果更新无法解决问题，请尝试删除任何可能导致问题的样式。它也可能是一种风格问题。

我知道已经晚了，
但是对我来说，只有xmlns的更改有所帮助。
xmlns产生与所述相同的错误：
xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"
对我有用的xmlns（与您使用的相同）：
xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
