WCF Document
Things to Cover:
1. What is WCF?
2. Why it is required?
3. What are the key components?
4. What are the steps to move ahead?
WCF
WCF (Windows Communication Foundation), which has code-named Indigo, is a technology by which pieces of software can communicate with one another.
Windows Communication Foundation consists of several new sets of classes added to the second version, the 2.0 version, of the Microsoft .NET Framework Class Library.
The Windows Communication Foundation has been released concurrently with the Windows Vista operating system in the second half of 2006, as part of a package called WinFX.
Requirement
It gives the feature of Web services as well as .Net Remoting. Looking into core - Windows Communication Foundation provides a software factory template for software communication, consisting of a modeling language called the Service Model, and a programming framework called the Channel Layer. One can configure the endpoints defined by an address, a binding, and a contract just by using configuration file.
Key Components
There are three Pillar of Indigo: -
1. Productivity: - When we say productivity, we are talking about bringing together the various technologies available today for building distributed applications. It’s importance: -
* Reduce complexity by allowing us to focus on single programming model rather than learn multiple programming models.
* It allow us to use single programming model for building distributed application that communicate with one another on single machine, across multiple machines, and across the internet.
2. Interoperability and Integration :- By this term I mean that Indigo enables us to build services that speak advance web services protocols(WS-*), enabling your application to communicate with other WS-* compliant services running on other platform. It’s importance: -
* The ability to communicate with application running on other platforms provides you with the flexibility you need when working in heterogeneous environment.
3. Service Orientated Development: - Indigo uses attribute based programming to
Define your services; you can dramatically reduce the amount of code you write
To build secure, reliable service. It enables us to develop loosely coupled service
And config based communication.
Steps to move ahead
Step 1] Install .NET framework 3.0
You can download the 3.0 version of the .NET framework from the following link
http://www.microsoft.com/downloads/details.aspx?familyid=10CC340B-F857-4A14-83F5-25634C3BF043&displaylang=en
Step 2] Install Microsoft SDK for .NET 3.0
You can download the 3.0 .NET SDK from the following link
http://www.microsoft.com/downloads/details.aspx?FamilyId=C2B1E300-F358-4523-B479-F53D234CDCCF&displaylang=en
Step 3] Install Visual Studio CTP Extensions for .NET Framework 3.0
You can download the Extensions ( WCF and WPF ) for .NET 3.0 from the following link
http://www.microsoft.com/downloads/details.aspx?FamilyId=F54F5537-CC86-4BF5-AE44-F5A1E805680D&displaylang=en
These 3 steps take care of the necessary software requirements that are needed to run WCF on your machine.
In my next article I’ll try to cover up the details of developing the WCF application.
As for now this is my first article. I hope it will help you to get aware about where we are moving. Any comments and questions are welcome.
