每次我尝试将C＃类添加到项目时都会发生这种情况。它是WPF，当我开始一个新项目时，它只能用窗口运行。在我尝试向应用程序添加实际功能的那一刻，它就像这样吹嘘我。（哦，它构建，它构建得足够公平 - 这是一个运行时错误。）即使我删除了类，应用程序仍然无法正常运行。 Wat do？

感谢任何帮助。

其他信息：找不到资源'mainwindow.xaml'。

您的App.xaml：

<Application x:Class="markless.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">

问题不是添加任何类，而是删除/重命名MainWindow，这里仍然引用。
