New Post: DateTimePicker issue

Hi, I've an application that uses DateTimePicker. Only on a certain computer, when the UI which contains DateTimePicker is opened, then the application crashes.

To prove that it is the DateTimePicker, I created a test app with just one dialog which contains only a DateTimePicker. Run the test app on the problematic PC, and it crashes as soon as I set the DateTimePicker to any date.

I already have a global error handling (intercepted through DispatcherUnhandledException, Dispatcher.UnhandledException, AppDomain.CurrentDomain.UnhandledException, TaskScheduler.UnobservedTaskException) but they didnt catch the exception thrown by DateTimePicker. The error message that I retrieved from windows event log:

Description: The process was terminated due to an internal error in the .NET Runtime at IP 73494B0D (73480000) with exit code 80131506.

I've tried capturing the crash dump using procdump -ma -e but nothing is captured.

PC info where I encountered the issue:

• Windows 7 x64
• .NET Framework 4.5 (tried repairing this but still no luck)
• WpfToolkit 2.3 (Community)
  

Any idea on how to fix this? Thanks in advance.
