C# and WPF - 'System.Reflection.TargetInvocationException' occurred in PresentationFramework.dll
提问by phil
I am working on a wpf application with visual studio 2012. The program had been starting up just fine until now. I had just finished adding a decent amount of code, and I hadn't started the program in a while. When I attempted to, I got a System.Reflection.TargetInvocationException. I tried to step into the code, but I got the message "PresentationFramework.pdb not loaded".
我正在使用visual studio 2012 开发一个wpf 应用程序。该程序直到现在才启动得很好。我刚刚添加了相当数量的代码，而且我已经有一段时间没有启动该程序了。当我尝试时，我得到了 System.Reflection.TargetInvocationException。我试图单步执行代码，但收到消息“PresentationFramework.pdb 未加载”。
I tried 'Start without debugging'. This time I got no exception, but it just didn't do anything. I have tried commenting out portions of my code to find the problem points, but I made no progress.
我试过“不调试就开始”。这次我没有例外，但它只是没有做任何事情。我曾尝试注释掉部分代码以找到问题点，但没有取得任何进展。
The code I had just added had nothing to do with wpf, if that has anything to with it.
我刚刚添加的代码与 wpf 无关，如果与它有关的话。

Try to start debugging from Window.Initializedevent
尝试从Window.Initialized事件开始调试
private void Window_Initialized(object sender, EventArgs e) {
int a; //put breakpoint here
}
XAML code:
XAML 代码：
<Window x:Class="ProjectName.MainWindow" ... Initialized="Window_Initialized">
