What I understand about WCF is right or not ?

Hi,

I am read about WCF and I want to ensure from I am read , if I understand concept right or not ?

What I understand about WCF is :

I understand that WCF has been build upon the previous technology like com,dcom ,.net remoteing ,msmq and web services so Microsoft group all this technology in one technology to increase flexibility .


the problem of SOA is that if you have different component and all component build on com technology and you want to change any component from those you will need to change other's like the new where WCF remove Independence between component so if have old components was built on com and you want to add new component use web services you doesn't have any problem to add where using WCF give capability to act with different component build on different technology.

I believe what is being said is that WCF has been developed from the experiences gained from those earlier technologies, but not necessarily built from them.

is this true

No

Here's a nice MSDN article to get you started:
http://msdn.microsoft.com/en-us/libr...(v=VS.90).aspx
(WCF Conceptual Overview - What is WCF?)

Some quotes from the article that relate to your Q:

Quote:

The foundation for new Windows-based applications is the .NET Framework. Accordingly, WCF is implemented primarily as a set of classes on top of the .NET Framework CLR. Because it extends their familiar environment, WCF enables developers who create object-oriented applications using the .NET Framework today to also build service-oriented applications in a familiar way.

[On interoperability...]
While WCF introduces a new development environment for distributed applications, it is designed to interoperate well with the non-WCF applications. There are two important aspects to WCF interoperability: interoperability with other platforms, and interoperability with the Microsoft technologies that preceded WCF.

[...]

Installing WCF does not break existing technology, so there is no requirement that organizations change existing applications to use it. A clear upgrade path is provided, however, and wherever possible, WCF interoperates with those earlier technologies.
