This is because the 'StartingUp' event changed to 'Startup' in the more recent WPF release. You can simply edit the avalon.py file and change app.StartingUp to app.Startup. --Steven

I installed the latest .NET 2.0 (final) and WinFX libraries and got the following error. I look similiar to Robert Smithson problems (http://www.mail-archive.com/users@lists.ironpython.com/msg00201.html). Robert says that he installed WinFX SDK and it worked. However I have SDK installed...I think. I mean WinFX SDK is called officially : MS Windows SDK for November 2005 WinFX RC CTP , right? I know avalon is working because XAMLPad from SDK runs fine. ............................................... Microsoft Windows XP [Wersja 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp.
