In C#, I'm trying to load a png file on Mac OSX using the latest Mono

using System.Drawing;
Bitmap bmp = new Bitmap("test.png");

I get the following error

Either the image format is unknown or you don't have the required libraries to decode this format [GDI+ status: UnknownImageFormat]

It doesn't happen with all png files; just this one.
alt text

Resaving in photo shop doesn't fix it unless I switch to 8bpp. Is there something I need to install to support this "special" png file? Works fine on windows.

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
