C# 窗口初始化时发生XamlParseException

当我打开我的WPF窗口时，我遇到了这个错误，我不知道是什么造成了这个错误，也不知道如何消除它。错误突出显示并指向底部的

'Initialization of 'Outlook_Add_In_Test.WPFExiEvent' threw an exception.' Line number '91' and line position '11'.

继续你在评论中所说的，它似乎与MahApps Metro主题有关

看看这个：

如果引用了Windows交互dll，请尝试将其删除

---

以后记得像SLaks说的那样检查InnerException。你可以从中学到更多，并为你提供更多的工作机会。

也许对某些人来说，这会很有用。今天我遇到了同样的问题：

项目中的“XamlParseException on window initialization”，nuget引用MahApp。 我试着重新保存包，删除引用，但没有任何帮助

在5月份的案例中，问题出现在app.config中。当我删除这些行时，问题消失了：

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Windows.Interactivity" publicKeyToken="31bf3856ad364e35" culture="neutral"/>
        <bindingRedirect oldVersion="0.0.0.0-4.5.0.0" newVersion="4.5.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

有人知道为什么会发生这种情况吗？

我认为您刚刚导入了错误的dll（NET40）。尝试导入最新的MahApps.Metro.dll（NET45）

---

对我来说，我将MahApps.Metro降级为1.6.4版，错误消失了 我以前使用的是1.6.5版

---

MahApps.Metro.Resources的版本是0.6.1

请阅读InnerException。{“MahApps.Metro.Behaviors.StylezedBehaviors”的类型初始值设定项引发了一个异常。}然后StylezedBehaviors的静态构造函数中有一个问题请阅读InnerException。谢谢。移除它确实有效，但是我的一些新东西已经停止工作。我将更深入地研究它。
