Www.xfront.com/REST-Web-Services.html. I will first provide a brief introduction to REST and then describe how to build Web services in the REST style.
What is REST? REST is a term coined by Roy Fielding in his Ph.D. dissertation  to describe an architecture style of networked systems. REST is an acronym standing for Representational State Transfer. Why is it called Representational State Transfer? The Web is comprised of resources. Getting Started Tutorial. The topics contained in this section are intended to give you quick exposure to the Windows Communication Foundation (WCF) programming experience.
They are designed to be completed in the order of the list at the bottom of this topic. Working through this tutorial gives you an introductory understanding of the steps required to create WCF service and client applications. A service exposes one or more endpoints, each of which exposes one or more service operations. Data Transfer Object. Version 1.0.1 GotDotNet community for collaboration on this pattern Complete List of patterns & practices Context You are designing a distributed application, and to satisfy a single client request, you find yourself making multiple calls to a remote interface, which increases the response time beyond acceptable levels.
Problem How do you preserve the simple semantics of a procedure call interface without being subject to the latency issues inherent in remote communication? Forces. A RESTful Web service, an example. It's often hard for people to "get" REST, this is mostly due to the fact that REST isn't a tangible thing like a piece of software or even a specification, it's a selection of ideals, of best practices distilled from the HTTP specs.
I've always found that the best way to understand something is to see an example, to see the principles in action first and worry about the details later once I understand the general gist. So here's a little example of a RESTful version of a simple Web service you might already know about, the Delicious API. How to define global variable in C# - C# C# - what is Entity Framework with POCO. PhoneBookService Service. POCO Support. What is the Difference Between a DTO and a POCO? First off, I’m not the authority on DTOs, POCOs, object oriented architecture, or really anything now that I stop to think about it.
However, I do use a DTO / POCO centric architecture whenever I can and there’s at least one former client of mine who is now saddled with an entity class named DevicePoco (there was already a Device entity object that followed the Active Record pattern, otherwise I would never have named an object XXXPoco). When my client saw the new object with the crazy name in their BAL, their first reaction was of course to ask “What the heck is a POCO?” Not too long ago I was at a Visual Studio User Group meeting where the question of POCOs and how they are different from DTOs came up. The presenter, who quite honestly is a much better developer than me, stated confidently that POCOs and DTOs are the same thing.
I immediately clamped both hands over my mouth to keep from screaming “They are not!”. 5 Minute Introduction to ASP.NET MVC. Plain Old CLR Object. Plain Old CLR Object or POCO is a play on the term POJO, from the Java EE programming world, and is used by developers targeting the Common Language Runtime of the .NET Framework.
Similar to the Java context, the term is used to contrast a simple object with one that is designed to be used with a complicated, special object framework such as an ORM component. Another way to put it is that POCOs are objects unencumbered with inheritance or attributes needed for specific frameworks. In .NET terms, the word is most often used in the programmatic sense, to differentiate a non-Serviced Component (see MTS) from a "standard object".
