How do I use the GDI+ blur effect on a .NET Bitmap?

Question

I need to apply a blur to a System.Drawing.Bitmap. The classes in System.Drawing are supposed to be wrappers around GDI+, so I'd I use the GDI+ Blur effect. Is this possible, and if so, how?

Edit: I don't want to know how to write my own Blur effect, I want to know how to use the built-in GDI+ one.

Take a look to this Codeproject article:Image Processing for Dummies with C# and GDI+ Part 2 - Convolution Filters

I realize this is yet another suggestion that does not show you how to use GDI+ Blur, but I honestly cannot find it myself. I can see the reference in MSDN and the OS list for the Blur class in GDI+ only goes up to Win 2000. Perhaps it just doesn't exist anymore. If this helps at all, here is an EXCELLENT link on implimenting your own Blur in C#

If that's not fast enough then give this a try:
