【问题描述】：
几个小时后，谷歌搜索并尝试返回以前的代码，我无法解决这个奇怪的异常。所以我愿意接受任何建议。
我对我现有的 ClickOnce-Deployment 项目进行了更新，并且在 Debug 中一切正常。完成更新后，我想在自己的网络中测试该应用程序，因为它是一个多用户应用程序。事实证明，我一定是在此过程中破坏了一些东西，因为我没有备份旧代码，所以我无法回滚。
我在 App.xaml.cs 中添加了一个异常捕获代码以写入日志，因此如果用户遇到异常，我可以检查日志并采取相应措施。这是以下日志的来源：
Zeilennummer "8" und Zeilenposition "9" von "Durch den Aufruf des Konstruktors für Typ "MietPlaner2020.MainWindow", der den angegebenen Bindungseinschränkungen entspricht, wurde eine Ausnahme ausgelöst."。 bei System.Windows.Markup.XamlReader.RewrapException（异常 e，IXamlLineInfo lineInfo，Uri baseUri） bei System.Windows.Markup.WpfXamlLoader.Load(XamlReader xamlReader, IXamlObjectWriterFactory writerFactory, Boolean skipJournaledProperties, Object rootObject, XamlObjectWriterSettings settings, Uri baseUri) bei System.Windows.Markup.WpfXamlLoader.LoadBaml(XamlReader xamlReader, Boolean skipJournaledProperties, Object rootObject, XamlAccessLevel accessLevel, Uri baseUri) bei System.Windows.Markup.XamlReader.LoadBaml(Stream stream, ParserContext parserContext, Object parent, Boolean closeStream) bei System.Windows.Application.LoadBamlStreamWithSyncInfo(Stream stream, ParserContext pc) 北 System.Windows.Application.DoStartup() bei System.Windows.Application.<.ctor>b__1_0（未使用对象） bei System.Windows.Threading.ExceptionWrapper.InternalRealCall（委托回调，对象参数，Int32 numArgs） bei System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)
在我的谷歌搜索中，我找到了这个英文翻译：
在匹配指定绑定约束的类型“TestWPF.MainWindow”上调用构造函数引发异常。
MainWindow-Constructor 的代码是这样的
public MainWindow()
{
InitializeComponent();
DataContext = this;
CheckInstallation();
//Min Window Size
MinHeight = 720;
MinWidth = 1280;
CurrentlyShownDates = new List<DateTime>();
CurrentDate = DateTime.Today;
DayPickedDirectly = false;
AddScrollBarColumn();
LoadData();
}
Row-Number "8" 和 Row-Position "9" 无论如何我认为这些行不合逻辑。它从来不是一个=-符号，只是代码中的一个随机字母，所以我真的不知道该怎么做。
由于它仅在安装应用程序时发生，我无法使用调试器检查代码，因为我无法在部署之前重现异常。
提前致谢，希望我能解决这个问题。
正如 Stephan 所问，这里是 MainWindow.xaml：

【问题讨论】：
-
能否请您也添加相应的 XAML？
-
感谢 XAML。我没有看到任何明显“奇怪”的东西……我认为我们需要更多细节。尝试记录 InnerException(s)（只需使用
ex.ToString()），以便我们在此处获得有关真正问题的更多信息... -
谢谢你，我使用 ex.Message + ex.StackTrace 和 ex.ToString() 我现在得到了这一行：
Zeilennummer "8" und Zeilenposition "9" von "Durch den Aufruf des Konstruktors für Typ "MietPlaner2020.MainWindow", der den angegebenen Bindungseinschränkungen entspricht, wurde eine Ausnahme ausgelöst.". ---> System.DllNotFoundException: Die DLL "SQLite.Interop.dll": Das angegebene Modul wurde nicht gefunden. (Ausnahme von HRESULT: 0x8007007E) kann nicht geladen werden.所以我知道问题出在哪里，现在我只需要让我的 Nuget 包再次显示...
