Commented Issue: Could not load file or assembly Xceed.Wpf.Toolkit.Aero2 [19506]

Hi,

I added the DoubleUpDown control to a DataGrid and when the first row is initialized I get following IO Exception:

> Could not load file or assembly 'Xceed.Wpf.Toolkit.Aero2, Version=1.9.0.0, Culture=neutral, PublicKeyToken=3e4669d2f30244f4' or one of its dependencies. The system cannot find the file specified.

When I continue, the application runs anyway and the control is shown and works. Do you have any idea what causes this exception and how I can get rid of it? If you need specific code I can provide it.

I use Caliburn.Micro as the underlying framework. The dll mentioned in the exception is nowhere to be found and it's not available in the zip that is provided on this webpage. I installed Extended WPF Toolkit via NuGet.

Cheers,
Daniel Fox

Actually I can't provide a working example, because the exception was thrown only when the application was started via VS 2012 from the directory it was in initially. No one else at my project could reproduce this problem and I can't reproduce it too after moving to another dir. I propose closing this issue, if I can reproduce it one more time somehow I will reopen it.
