What is WF series? [build a data logic layer based on WF and WCF] What is WF? Many people who have some knowledge about NET technology can say something, but they cannot make it clear. No matter what you think WF is, do not compare it with Jbpm, Shark, Biztalk, and SharePoint. These products share the same characteris

[Stick to the top] Keep learning WfArticleIndex I think there is nothing to write about this article. I think it's a big hat. If I say it's too simple, there's nothing to do with it. I can't finish writing it, and I just can't go deep into it (:-)). WF is a scalable framework and is designed for scalability at every level from bottom to top. WF provides a workflow engine, A.

No task table pairWFImpact In section 3.1, when considering task allocation, WF does not have the concept of a task table, and the WF engine does not care when the process is transferred or where it is transferred. This is so far. This design is very good, but WF does not provide a task table to deal with the retrieval of tasks, which has a great impact. It is n

The most typical application of transactions is in relational databases. Compensation is an operation that has been successfully canceled. In our workflow, we may complete a task consisting of many activities. For example, our activities all use transactionscopeactivity, and

Sometimes it takes a long time, so we cannot keep the workflow instance in the memory, which requires persistence. Workflow persistence stores certain State information of a workflow to persistent storage, such as SQL databases and files. Once saved to persistent storage, the workflow can be removed from the memory, load as need

How to Learn WF After the release of NET4.0 Bata 2 in March October, I began to write the [WF4.0 Basics] series. After more than five months, I finally completed the series before the official release of NET4.0. During this time, I had some conversations with developers and companies interested in WF4.0. Some companies that are interested in WF have started to use WF4.0 to develop business process manag
