c# - 为什么 System.ServiceModel.Persistence 过时了？

Question

我正在研究为 WCF 创建自定义持久性提供程序，但是 according对于 MSDN，整个程序集都已过时。我似乎找不到原因，也找不到关于应该使用什么来代替它的建议。谁能告诉我为什么这已过时以及我可以使用什么来替代？

Answer 1

documentation的每个部分你链接说:

The WF3 types are deprecated. Instead, please use the new WF4 types from System.Activities.*

更多信息来自 Jurgen Willis, MSDN :

In .NET 4 the Workflow Team released an all new Workflow engine in the System.Activities namespace. This new Workflow technology, which we refer to as WF4, responded to key customer feedback by providing significant programming model, runtime, and authoring enhancements.

With the release of .NET 4.5 Beta we are marking the types in the “WF3”, System.Workflow, namespace as obsolete.

Customers who want to migrate their applications to WF4 will find help in the WF 4 Migration Guidance articles on MSDN and the WF Migration Kit on the WF CodePlex site.
