Windows Workflow Foundation (WF)

"Workflow" is a declarative way of implementing result oriented business process in software. WWF is a programming model that helps in defining, building, executing, debugging and managing work flow related applications that are in sync with business processes. It consists of a Microsoft NET Framework version 3.0 namespace, an in-process workflow engine, and designers for Visual Studio 2005.

We can build as many work flow styles as we need based on the requirement.

Graphical designer and debugger are provided to implement work flow related software. We can make use of imperative code along with declarative modeling.  It enables us to build workflow software that is more flexible and transparent.

Core Components

WF core components include:

1.      Base Activity Library: This provides functionality for control flow, conditions, event handling, state management and invoking web service. One can build his or her own custom domain specific activities using the base activity.

2.      Runtime Engine: This is responsible for Workflow execution and state management.

3.      Runtime Services: This provides hosting flexibility and communication.

4.      Visual Designer: It is responsible for graphical and code-based construction.

Once a workflow model is compiled, it can be executed inside any windows process including console applications, WinForms applications, Windows Services, ASP.NET Web sites, and Web services. Extensible Object Modeling Language [XOML] based on XAML is the language that is used for declaring the structure of workflow, business logic for the workflow.

In order to create workflow, activities using WWF are:

1. VS 2005 (comes by installing Visual Studio 2005 add-ins to design and program workflow)

2. SharePoint designer that permits building workflows for Share Point 2007

Hi HIma

Nice overview of .Net 3.0. Keep up the good work. This article is very good for starters for understanding the basics in clear and concise way. I am looking forward for more articles (especially on .Net 3.5 with more emphasis on LINQ and DLINQ). I guess, it would be great if you include a section called targeted audience. That way, it will reach the right people.

Hi Scott,
Thanks for the feedback .This article is written for beginners who are not aware of Framework 3.0. This describes features and components in 3.0.I think you are expecting practical oriented approach. I would be discussing on each part in my upcoming articles.

Date: 2007-07-11 4:07:43 AM
Good attempt. But lacks terribly the professional approach for a good article on a topic like .net 3.0. I expected much more than a brochure kind of article like this.
Anyway this is ok for starters.
Best wishes

Hi Keyyan,
You are right that Silverlight is not part of dotnetframework 3.0
It's neither mentioned in the features/figure.
Since it's Subset of WPF ,and recently released I just gave an introduction on it.It doen't mean that it's a part of DotnetFramework 3.0.
As mentioned Framework 2.0 is unification of BCLs+ CLR 2.0+ Framework 2.0+ WPF+WWF+WCF+WCS
Thanks for the feedback
Title: Silverlight

Date: 2007-07-10 12:50:52 AM
But Silverlight isn't a part of .NET Framework 3.0 and it seems that you're considering it as a part of .NET 3.0.
