ClickOnce related

Question

After publishing a WPF application to a central location using ClickOnce, I am getting following exception when user tries to access the application. There are other applications, which works fine for them and issue is only when they access a particular application.

I can't workout why this hence the exception doesn't seems to be very helpful.

This is fixed now. Following is the solution for the mentioned issue.

Application was crashing after downloading and before starting up. In order to pin point, I enclosed DispatcherUnhandedException handler to know more about it. With following in place, I was able to nail down the exact exception from the log file. In my case, it was to do with virtual machine profile permission. It might be totally different in your case. However, this approach will give you a helping hand to filter the root cause.

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

and

void ApplicationDispatcherUnhandledException(object sender, System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e)
        {

            var theException = e.Exception;
            var theErrorPath = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) +"\\IntraDataCopyError.txt";
            using (System.IO.TextWriter theWriter = new System.IO.StreamWriter(theErrorPath, true))
            {
                var theNow = DateTime.Now;
                theWriter.WriteLine("Error log at : " + theNow.ToShortDateString() + " " + theNow.ToShortTimeString());
                while (theException != null)
                {
                    theWriter.WriteLine("Exception: " + theException);
                    theException = theException.InnerException;
                }
            }
            MessageBox.Show("The program aborted due to following issue.\n" + theErrorPath);
            e.Handled = true;
            Application.Current.Shutdown();

        }
