The resource file you've attached can't be correctly read by MS.NET 2.0,
so I doubt this is a bug.

When I try to read the resource on MS.NET 2.0 with the following
code, I get "true". This means that MS.NET was not able to deserialize
the value.

using System;
using System.Collections;
using System.Resources;

class MainClass
{
         static void Main ()
         {
                 ResXResourceReader reader =
                         new ResXResourceReader("test.resx");

                 foreach (DictionaryEntry e in reader) {
                         string key = (string) e.Key;

                         if (key == "WebReference.File.Wsdl.png") {
                                 Console.WriteLine (e.Value == null); 
                      }
                 }

                 reader.Close();
	}
}


If I apply the attached patch to Mono's ResxResourceReader
it will be able to deserialize such values, but that's not
compatible with MS.NET, so it's rather useless.

MS.NET seems to use binary serialization for System.Drawing.Bitmap.
It generates the attribute

mimetype="application/x-microsoft.net.object.bytearray.base64"

which can be deserialized by Mono w/out any trouble.
