Workflow Foundation 4.0 Activity Data Model (II)

Here comes sequal of my WF4 Activity Data Model blog. This post focuses on WF arguments: the Argument class hierarchy which models arguments for WF; how to "declare" an argument for an activity; the automatic reflection; how to deal with dynamic arguments; what does expressions mean for WF; how to bind arguments to expressions; activity arguments evaluation order, and etc. 

The next post will be about WF variables.
