This is a library of blend modes that can be used with WPF 4.0 (and forward).
I recently went through and compiled all the HLSL effect (.fx) files into pixel shader (.ps) files. This means that the library is now really a standalone library that you can just easily use in your WPF projects. I don't know why I haven't done this before!
I have a series of blog posts that describe these blend mode effects ... and which also details the journey in creating the library itself.
If you happen to use my library, I would love to hear about it. It was a labor of love!
