CreateBookmark()返回两者中的哪一个？为什么是特殊情况？ 从其行为和 .NET Reflector。
An ActivityExecutionContext has three ways of creating bookmarks: CreateBookmark, CreateNamedBookmark and CreateProtocolBookmark.
- Which one is supposed to be used for what kind of asynchronous operation?
- What is the difference between a named and a protocol bookmark?

CreateBookmark()return and why the special case? It appears to behave like an named bookmark only without the name part judging from its behavior and .NET Reflector.

目前BETA 1刚刚发布，到目前为止我只看到了异步操作的createNamedBookmark的示例。

MSDN 没有该协议的文档框架，所以我想目前只有 WF Core 团队可以回答你的问题。 否则，您将不得不等到下一个版本。

As of now BETA 1 is just released, and so far I have seen only examples of createNamedBookmark for asynchronous operation.

There is no documentation from MSDN for the protocol framework, so I guess only WF Core team could answer your question as of now. Otherwise, you will have to wait till the next release.
