Vista - How catch unhandled Exception in WPF Project

I my Forms Application I catch unhandled Exceptions this way and show them
in a custom ErrorDialog:

Public Shared Sub Main()
AddHandler System.Windows.Forms.Application.ThreadException, AddressOf
OnVitoThreadError
AddHandler AppDomain.CurrentDomain.UnhandledException, AddressOf
OnVitoUnhandledError

Try
m_Application = New MyCustomApplication
m_Application.Run()
Catch ex As Exception
ErrorDialog.ShowError(ex)
End Try
End Sub


Private Shared Sub OnVitoUnhandledError(ByVal sender As Object, ByVal e As
UnhandledExceptionEventArgs)
MyErrorDialog.ShowError(ex)
If e.IsTerminating Then Environment.Exit(-1)
End Sub

Private Shared Sub OnVitoThreadError(ByVal sender As Object, ByVal e As
System.Threading.ThreadExceptionEventArgs)
LogFacade.LogCriticalError("Nicht behandelter Fehler ThreadException",
e.Exception)
MyErrorDialog.ShowError(e.Exception)
End Sub


If I do the same Sub Main in a WPF Project my Error never will shown.
What kind of Event I have to handle?

You may have to work with App_DispatcherUnhandledException. I was
just reading about it today, I haven't used it yet.

Take a look at http://msdn2.microsoft.com/en-us/library/ms743714.aspx
for an example of how it's implemented. It's about half way down the
page.

Hi Mark

Thanks a lot for your answer.
I find yesterday the DispatcherUnhandledException and build a simple project
to find a way to solfe the problem.

In my application i start a new thread to show the windows.
And I think thats the reason why it dons't work (At designtime it works. on
runtime not)
Do you know how I have to handle exceptions in thread.
See my sample project in the attachment.

Best regards

I'm sorry Horst, unfortunately I don't know how to do this yet. I haven't
had a chance to play around in this area.
