Building data logic layer based on WF and WCF

What WF is, many people who know about net technology can say a little, but not clear

No matter what you think WF is, but do not compare with jbpm, Shark, biztalk,sharepoint These products have the common characteristics of enterprise business process application products, WF is not, WF oriented developers

WF is a process-controlled development platform that uses XML descriptions with IOC and AOP capabilities.

I have been engaged in workflow development for 8 years, learning WF has been 5 years, in the blog Park to write about WF theme blog for nearly 4 years, since the contact with WF I have been explaining the difference between WF and traditional workflows

Maybe I am engaged in workflow development, from learning WF, while also using WF to develop workflows, so many people who look at my blog mistakenly think WF is like JBPM, Shark, biztalk,sharepoint These products are dedicated to the development of enterprise business processes.

The articles listed above are marked with a writing date to prove that I have been explaining the problem to you, but now it seems not enough. So I decided to write another series, with a few specific applications to fully introduce WF

(I don't repeat what I've written before, and I want to know WF's friends can look at the articles listed above.)

If you are developing a friend of COM +, looking at today's example, you will find this example very much like the idea of building a data logic layer with COM +.

In fact, wf3.x + WCF is an alternative to COM +, but to WF4.0 some changes, MS provides a stand-alone service for the release of WCF and WF, this way than wf3.x + WCF more like COM +, which I later write a series, the following look at the example of this article
