Seit einigen Tagen ist die Windows Workflow Foundation Beta 2.2 verfügbar, welche mit Office 2007 Beta 2 kompatibel ist, jedoch nicht mit den Bits des WinFX CTP vom Februar.

Microsoft Archtitecture Journal Issue 7 ist seit kurzem verfügbar - die Themen: SOA und Workflow.

Informationen zum Thema Windows Workflow Founation und ASP.NET sind bisher noch sehr dünn gesäht.

Darum hier zwei Links, die sich mit dem Thema befassen:

• Windows Workflow Foundation, Part 2 von Dino Esposito
• Using WF to run a page-flow von Jon Flanders (via Andreas/glengamoi)

Using Windows WF, you can create processor flow-based workflows and host them in any type of .NET application. ASP.NET developers face a unique set of issues that can benefit from workflows, such as maintaining state and page navigation.

Todd Kitta shows a sample implementation of the MVC Pattern using WF and ASP.NET in his devx article "Working with Windows Workflow Foundation in ASP.NET"

In addition to the WinFX November CTP, Microsoft has released the Microsoft® Visual Studio® 2005 Extensions for Windows Workflow Foundation Beta 1.2 for Microsoft Pre-Release Software WinFX® Runtime Components - November Community Technology Preview (CTP).

The Visual Studio 2005 Extensions for Windows Workflow Foundation are required for customers who are designing workflows in Visual Studio 2005 and/or require the Windows Workflow Foundation SDK.

"Windows Workflow Foundation is the programming model, engine and tools for quickly building workflow-enabled applications on Windows. It consists of a Microsoft® WinFX® name space (System.Workflow), an in-process workflow engine, and designers for Microsoft Visual Studio 2005. Windows Workflow Foundation is available (currently as Beta) for both client and server versions of Windows. Windows Workflow Foundation supports a wide range of scenarios including workflow within line-of-business applications, user interface page flow, document-centric workflow, human workflow, composite workflow for service-oriented applications, business rule-driven workflow and workflow for systems management.

There are two downloads on this page:

• The Windows Workflow Foundation Beta 1.2 runtime components are required for Microsoft Windows SharePoint Services "3.0" (Beta 1), Office "12" servers (Beta 1), and "FrontPage 12" (Beta 1).
  
• The Visual Studio 2005 Extensions for Windows Workflow Foundation are required for customers who are designing workflows in Visual Studio 2005 and/or require the Windows Workflow Foundation SDK."

The following well-hidden Hands-On-Labs are available now:

• Windows Presentation Foundation
• Windows Workflow Foundation
• ASP.NET Atlas
• LINQ
• DLinq
• XLinq

WinFX Documentation is online now and includes the Windows Workflow Foundation Documentation based on beta 1 bits.

On Channel9 there are two screencasts showing you key concepts and basic samples of Windows Workflow Foundation:

Hello Workflow - Windows Workflow Foundation key concepts:

"Windows Workflow Foundation is a component of WinFx that allows you to add workflow functionality to your applications.   In this screencast, James Conard, shows a simple "Hello Workflow" example that demonstrates the key concepts of Windows Workflow Foundation including:  activities, workflow models, and hosts.  You will also see how Windows Workflow Foundation provides visual debugging of workflows."

State Machine Workflow Example (Order Processing App):

"The State Machine workflow functionality provided with Windows Workflow Foundation provides a powerful way to model the control flow of applications.   In this screencast, James Conard, shows an example Order Processing application that utilizes a State Machine workflow for managing the states of an order.   The demo also shows how an application can have visibility into running workflow and even change the steps (activities) within a workflow dynamically."

The source code for the second screencast and other samples are available for download from here.
