WPF应用程序OnStartup中System.IO.FileLoadException的原因

Question

我正在调试一个WPF应用程序,它在启动时会因未处理的System.IO.FileLoadException而崩溃.

我使用程序集绑定日志查看器来验证没有程序集加载错误,并且OnStartup覆盖中的所有代码都包含在try catch中.

排除大会绑定作为异常的原因,我应该研究其他可能的原因是什么？

以下是相关的事件日志条目:

Answer 1

只是猜测，但我之前曾见过损坏的 user.config 文件在另一个应用程序中执行过类似的操作。那是不久前的事了，我不记得抛出了什么异常。检查 AppData 目录（或其他位置）中是否有一个并将其删除。
