I've said a lot of time in the past that one of the key concept of many enterprise project in the near future will be this word: Workflow.
Microsoft has developed a complete Framework called Windows Workflow Foundation (now WF), a general purpose programming framework for creating reactive programs that act in response to stimulus form external entities. WF programs are constructed using domain-specific program statements called activities.
WF will the the base to create workflow systems on the future Microsoft platforms (Sharepoint 2007 and CRM 4.0 will use the platform natively for example) and so it's a concept that I want to understand and learn well.
My first step on learning WF is reading this book:
It's on my desk from few hours and the first impressions are that it's well done and really interesting to read (it discuss a lot also the underlying WF architecture).
Something new to read for the next evenings...
