c#, wpf 4.0 EventType : clr20r3 P9 : system.windows.markup.xamlparse

Question

Hi. 

I've created a wpf 4.0 app with c# and I have this problem.

When i debug and run my app throug vs2010, there is no problem.

But if i try to run the .exe file, it crashes, and the error report is 

EventType : clr20r3     P1 : application.exe     P2 : 1.0.0.0    

P3 : 4ee325f2     P4 : mscorlib     P5 : 4.0.0.0     P6 : 4e181ae3     P7 : 41ed

P8 : 460     P9 : system.windows.markup.xamlparse     

 

What is going wrong? 

Answer 1

Handle DispatcherUnhandledException event in Application.xaml to get cause and location of the error.

XAML File

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

Code behind

public partial class App : Application
{
    void App_DispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
    {
         MessageBox.Show(e.Exception.ToString());
    }
}

I found solution to my problem

I went to Debug --> Exceptions, added System.Windows.Markup.XamlParseException and checked "Throw".

 

The problem was at the FileSystemWatcher, that I have to my app.

 

Khanna thanks for your suggestion, it helped me to another problem that I had.
