名称Metrowindow不存在？

Question

我遇到了一个错误：“The name metroWindow does not exist in the namespace:MahApps.Metro.Controls;assembly=MahApps.Metro”，我不知道问题出在哪里。我已经检查过使用NuGet替换了MahApps，但仍然存在同样的问题。我目前正在使用VS2012。我已经查看了一些Stack Overflow的问题，但问题仍然存在。

Answer 1

在我的情况下，通过基本的MahApps Nuget安装即可正常工作。因此，代码不是问题。尝试卸载MapApps Nuget，然后重新安装它，或者在Package Manager Console中运行以下命令：

Install-Package MahApps.Metro -Version 1.3.0

请记住，问题不在于你的代码，而在于你的配置。如果更新没有解决问题，请尝试删除任何可能导致问题的样式。这也有可能是一个样式问题。

我知道现在有点晚了，但是对于我来说只有更改 xmlns 才能解决问题。 xmlns 产生了与描述相同的错误：

xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"

适用于我的 xmlns（与您使用的相同）：

xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
