XamlParseException in WPF application - but only on when installed on XP

Question

My WPF application is running fine on Windows 7. Installation on XP machine brings up the following error on startup:

Framework Version: v4.0.30319

Description: The process was terminated due to an unhandled exception.

Exception Info: System.Windows.Markup.XamlParseException

Stack: at System.Windows.Markup.XamlReader.RewrapException(System.Exception, System.Xaml.IXamlLineInfo, System.Uri)

at System.Windows.Markup.WpfXamlLoader.Load(System.Xaml.XamlReader, System.Xaml.IXamlObjectWriterFactory, Boolean, System.Object, System.Xaml.XamlObjectWriterSettings, System.Uri)

at System.Windows.Markup.WpfXamlLoader.LoadBaml(System.Xaml.XamlReader, Boolean, System.Object, System.Xaml.Permissions.XamlAccessLevel, System.Uri)

at System.Windows.Markup.XamlReader.LoadBaml(System.IO.Stream, System.Windows.Markup.ParserContext, System.Object, Boolean)

at System.Windows.Application.LoadComponent(System.Object, System.Uri)

at MyApplication.App.InitializeComponent()

at MyApplication.App.Main()

I think I may be experiencing the problem described in the answer to this question:

XamlParseException on Windows XP

as I am using PresentationFramework.Aero in places. Is there a way to fix this or will I have to remove Aero? This is a pain as I am using some ButtonChromes

TIA

i am having the exact same problem, have you found a solution that you can post an answer to your question? — KMC

I had the same problem on Windows XP SP3 and for me the problem was solved by setting the "Copy Local" property of the PresentationFramework.Aero reference to "True".

When referring to the ResourceDictionary for Aero, try specifying the full assembly name, not the short assembly name.

<ResourceDictionary Source="/PresentationFramework.Aero, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35,ProcessorArchitecture=MSIL;component/themes/aero.normalcolor.xaml" />

Make sure there are no exceptions being thrown in the constructors for any of the UI components (such as codebehind for .cs files).
Make sure if you're using MVVM that you're not throwing any exceptions in the ViewModel constructor.

I had a view model throwing an exception (related to a COM component [which I'm now going to go track down!]) that had NOTHING to do with Xaml at all. You'll get a XamlParseException if the creation of a Xaml based component fails - and it can be misleading.

FIX: An exception in the XAML parser is thrown when you run a WPF application on a computer that has customized English (United States) regional settings.
