Windows Workflow Foundation (WF): Hands-On

 
Course: 514     Type: Hands-On Training     Duration: 3 Days

Quick Enroll    

You Will Learn How To
  • Build dynamic and flexible applications using Windows Workflow Foundation (WF)
  • Assemble workflows with sophisticated logic using the Workflow Designer
  • Host workflows in Windows and Web applications
  • Apply local host communication services to workflow applications
  • Implement sequential and state machine workflows using WF
  • Employ the persistence and tracking services in WF

Course Benefits
Windows Workflow Foundation (WF), an integral part of Visual Studio 2008, offers a programming toolkit and runtime engine to assemble workflow-enabled applications that model business processes. In this course, you gain experience developing desktop and Web applications with WF. You learn how to write code to exchange data between the host application and running workflows, create custom WF activities, and persist and track in-flight workflows.

Who Should Attend
Programmers, system analysts and anyone developing .NET applications using WF. Programming experience at the level of Course 503, "Visual Basic 2008 Programming," or Course 419, "C# Programming," is assumed.

Hands-On Training
Through a progressive case study, you gain practical experience building WF-enabled applications. Exercises, completed in either VB or C#, include:
  • Designing business logic visually with the workflow design toolkit
  • Creating sequential and state machine workflows
  • Integrating WF with Windows and Web applications
  • Modeling business processes through custom activities
  • Implementing local communication services
  • Tracking and tracing workflow history
  • Persisting workflows into SQL Server
