I just ran into this behavior on Windows XP and WPF 4. There is no reason why this bug exists FIX it and don't close it by design.

Experienced the issue just now, on XP with .NET 4.0. To me it is absolutely not acceptable that such serious bugs can persist for so long. As pointed out earlier, WPF is hard enough to learn anyway, it shouldn't be necssary to deal with such problems.

I built an app and used an ico file that works on WIndows 7 and had the customer asking why the app crashes on XP.

also the same ico works on the first form the app opens but not on a second form? WTF?

the unrecognised image format exception at runtime is really nasty!
handle the exception at runtime and add a check when the app compiles that the icon format selected is not compatable with XP!

XP may be end-of-life today but there are a lot of PC's running XP that will still need to have apps installed on them for a while yet.

This was a pretty frustrating bug. Took an hour between me and another developer to find out this was flagged as a problem. As a new WPF user, it is hard enough to learn the new architecture but then to spin your wheels on an issue like this can generate a lot of disgruntlement.

When you deliver a package VS2008, WPF and a bunch of icons, that package shall be supported. It's that simple...

This is a stupid bug...I think...
WPF managed programs runs on Vista recommend, but not support Vista icons...

I understand that you have more cool features to do, but fixing it to not crash on ANY member access would be sufficient fix.
Right now there is no way to iterate over Frames collection without exception generating. In some scenarios event using try-catch approach is not solution as introduction of try-catch involves creation additional code.
ITS REALLY important to AT LEAST not throw exception. Better solution would be to be able programatically check for unsupported frame types/formats.

We can take the time to support custom Pixel Shaders, but not Vista icons?

This is a new icon format that was introduced with Vista and is not yet supported by WPF/Windows Image Codecs.
