, because that's the API you'll probably meet. In the remainder of the section, we will understand the components by making a REST API. Our first resource Recalling the 2nd Chapter, we talked a little bit about resources. Recall that resources are the nouns of the API (Customer and pizza). These are things that we want the world to interact with through the API. To feel how a company is starting to design the API, let's try to contact our

Just like the other creation patterns,It is also an issue in which objects are created without specifying object-specific types.The

In a previous blog post, Windows Server AppFabric introduced a brief introduction to Windows Server AppFabric. In this article, I'll explain how to host WF4.0 applications in Windows Server AppFabric, and how to persist configuration and trace configurations. First, I will use ASP.net and WF4.0 to implement a simple pizza ordering system. The application is then hosted on the Windows Server AppFabric to implement persistence, tracking, and so on.
