New Post: Put PropertyGrid attributes/interfaces into separate assembly

Nope,

That's not what I'm talking about.

I'm talking about attributes that WPFToolKit provide to provide generic functionality for item sources etc, and placing those attributes in their own assembly

eg:

http://wpftoolkit.codeplex.com/wikipage?title=PropertyGrid&referringTitle=Home#custom_itemssource
http://wpftoolkit.codeplex.com/wikipage?title=PropertyGrid&referringTitle=Home#custom_editors_attributes

In the WinForms propertyGrid, those attributes (eg DisplayNameAttribute, DescriptionAttribute) are in a assembly that is not attached to winforms so you are not locked into using winforms to use those attributes.
