The Windows Workflow Foundation (WF) has been introduced
as part of the .NET framework as a means of creating
workflow-centric applications. Its intended field of application
is broad, ranging from fat-client applications and web
applications to enterprise application integration solutions.
Unlike other approaches, Windows Workflow supports two
distinct approaches to workflow specification - sequential
workflows and state machine workflows - which deal with
fundamentally different types of business scenarios. To date
there has been minimal investigation into its capabilities
and limitations, especially with respect to the two different
control-flow styles it offers. To remedy this, in this paper
we present a rigorous analysis of Windows Workflows´s
ability to deal with common control-flow scenarios. As a
framework for this evaluation we use the Workflow Patterns.
Our analysis outlines the strength and shortcomings of Windows
Workflow´s control-flow expressiveness and compares
it to BPEL and jBPM - two other popular approaches for
the design and implementation of business processes in a
service-oriented context.
