Question

I have a problem with a BitmapImage in wpf. When i create it it gives a filenotfound exception, which says it’s missing the PresentationCore.resources assembly. But i’ve added it to my references list and it still throws the same exception

Uri filename = new Uri(@"D:\barcode_zwart_wit.jpg", UriKind.Absolute);
BitmapImage image = new BitmapImage(filename); //<-- FileNotFound Exception

• The image uri is correct.
• The image isn’t opened somewhere else
• I’ve checked the version of the PresentationCore.resources, no problem there.
• The lines are in the setter of a property, which is first launched in the constructor of a usercontrol.
• Visual Studio 2010, .net v4

Does anyone have any idea what’s the problem? Does PresentationCore.resources have any dependencies i don’t know about?

I’ve solved it by using AppDomain.CurrentDomain.AssemblyResolve. it’s an event which is called if a certain assembly can’t be found.

in constructor:

AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve);

CurrentDomain_AssemblyResolve:

Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
    string missingAssemblyName = args.Name.Remove(args.Name.IndexOf(',');
    if ( missingAssemblyName == "PresentationCore.resources" )
    {
         string s = "C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\PresentationCore.resources.dll";
         return Assembly.LoadFile(s);
    }
    return;
}
