In the previous article, I used examples to explain how to dynamically load xoml creation and running processes in. NET Framework 3.0 (3.5. This article introduces some important changes of WF 4 in WF 4.0.
In WF 4, XAML (note, not xoml) is used by default, and C # Code cannot be included at the same time.
In WF 4, s

WF can help you with the creation of these places, WF will not only execute the workflow instance you created, but will also help you to create them. WF
It's almost a month before the opening. Let's summarize the 60 articles published.WF is not a business platform, but a platform for developers to create workflow software. That is to say, WF is not a workflow application platform, but a platform for developing workflow applications.

Everyone knows that in WF, by default, its activities are composed of tree structures. Simply put, a composite activity contains its subactivities. If a subactivity is a composite activity, it can also contain its subactivities, however, a single activity cannot be a subactivity of two activities. This method is widely used in the activity library of WF, such as loop and conditional activity.This method has
After completing this chapter, you will learn:
1. Learn which components are required to create a full-featured custom workflow activity
2. Create a basic custom workflow activity
3. Apply validation rules in basic custom workflow activities
4. Integrate basic custom workflow activities into the Workflow View Designer and toolbox of Microsoft Visual Studio
WF is not likely to cover every aspect of what you might want to achieve in your workflow.

[WF] Quickstart sample Preface
Workflow Foundation (WF) always gives a very useful impression, but does not know how to use it. This is mainly because there are too many pre-jobs and a lot of underlying knowledge need to be integrated to complete writing: Execute activity, pause activity, re-read activity, continue activity, this series of workflow.
The following example is a record of my learning about Wor
