In last 20 years or so, most of the programming has moved from low level languages to high level languages. In today’s industry where programmers depend upon high level languages mundane tasks such as memory allocation and re writing the code for different machines, are things of past since the introduction of Microsoft’s .NET  common language run time which can compiled just –in- time to run on any machine natively.

Going back to days of C, once considered a sophisticated language (still is); managing information/data workflow was a tedious task and especially when the code has synchronization, callbacks and sub routines. Windows workflow foundation is a declarative framework just like user’s interface, which handles “behind the scenes” service logic and presents itself as an opportunity to develop code in high level language for asynchronous, parallel tasks and other complex processes.

WWF is a combination traditional and modern programming tools for declaring workflow, activities to help define the logic and control flow, and a run time for executing the resulting application definition. WF is about using a higher level language for writing applications, with the goal of making developers more productive, applications easier to manage, and change quicker to implement.  The WWF run time not only executes  workflow, it also provides services and features important when writing application logic such persistence of state, book marking and resumption of business logic, all of which lead to thread and process efficiency.

The WF programming model has been revamped to make it both simpler and more robust.  Activity is the core base type in the programming model and represents both workflows and activities.  Its no longer needed to create a Workflow Run time to invoke a workflow, it can simply be created as an instance and executed, simplifying unit testing and application scenarios where developer do not want to go through the trouble of setting up a specific environment.  Finally, the workflow programming model becomes a fully declarative composition of activities, with no code-beside, simplifying workflow authoring.

For web developers:

One of the benefits of WF is that it allows program application logic declaratively, but most people do not want to write XAML by hand, which is why the designer experience in WF is so important. Common scenarios where web developers mostly use .NET workflow functionality:

A) When different data sources (mostly databases) are a part of application’s work flow
B) Periodically changing application logic, where few steps in a workflow are modified
C) Isolated workflow outputs (branched design) that require complex logic
D) Batch inputs which are a part of initial workflow and have undefined time frame
E) Maximize productivity and agility of application concerning interoperability.

Advantages:

  • Flexibility
  • Run time reporting,
  • Integration with communication foundation,
  • Dynamic configuration,
  • Visual design of application logic,

Disadvantages:

Learning curve, most programmers face difficulty in adapting to workflow design techniques
