My MSDN article on communications in workflow has been posted. In this article, I really wanted to try and focus on the low level communication so that people would understand what was going on under the covers. I don’t both with the “local communications” pieces as they provide a simple abstraction on top of this underlying architecture.
I hope you find this useful. Any feedback is always appreciated, and if you have ideas for things you’d like to see in future columns, leave acomment here.
