The main purpose of this article isRehost WWF designerLater, I want users to see a more dedicated designer than the default one provided by Microsoft.ENote (at least the current version is like this ). Due to busy work, the design described in this article is not comprehensive, but only the title and text. I hope you will forgive me. However, for general applications, I think these can meet most of the requirements.

All appearance features are composed Designer Such as the prompt information in the activity center, text in the title, border, background color, and so on. Some of them are in Designer Specified in Activitydesignerthemeattribute Attribute. Set Designer Apply it to our custom activities, and we can see these effects. Example:

[Designer(Typeof(Mysequentialworkflowactivitydesigner),Typeof(Irootdesigner)]

Public Class Mysequentialworkflowactivity:Sequentialworkflowactivity

{

}
