Exception handling in windows application c# [duplicate]

Question

In a C# windows application I have written code to display all exceptions. I tried the code below. When running in trace mode (pressing F5) it worked (I have written my UI event functions which has created the exceptions). But when I run the standalone exe it does not catch the exception. Instead it is displayed as an unhandled exception.

static void Main()
{
    try
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
        MessageBox.Show(ex.StackTrace);
    }
}

Does anybody know about it?

You better use the unhandled exception handler:

AppDomain.CurrentDomain.UnhandledException +=
        new UnhandledExceptionEventHandler(CatchUnhandledException);
