I talk about something and it is misconstrued, and I get into trouble. That’s a nuisance.
I don’t know whom to believe
 I see no reason for using such harsh words
if i made a point and you must listen to it. i love the country  and that’s why i raised a concern
 i speak of my fear and insecurities of our j in the wake of the ‘growing intolerance’ 
  hundreds of people are worried about their families.“I am searching for new jobs as I am worried about my family.

WCF



What are the important principles of SOA (Service oriented Architecture)?

What are ends, contract, address, and bindings?

Every service must have Address that defines where the service resides, Contract that defines what the service does and a Binding that defines how to communicate with the service.

In WCF the relationship between Address, Contract and Binding is called Endpoint. The Endpoint is the fusion of Address, Contract and Binding.


1. Address : Specifies the location of the service which will be like http://Myserver/MyService.Clients will use this location to communicate with our service.

2. Contract : Specifies the interface between client and the server.It's a simple interface with some attribute.

3. Binding : Specifies how the two paries will communicate in term of transport and encoding and protocols.

WCF service endpoint consists of 3 things
A - Address (Address where the WCF Service is available)
B - Binding (We will discuss this in more detail in this video)
C - Contract (Specifies what the service can do. For example, the service contract describes which operations the client can perform on the service)



So, what is a binding in a WCF service?
WCF binding defines how the client needs to communicate with the service. The WCF binding that you choose determines the following for the communication between the client and the service.
Transport Protocol (for example, HTTP, TCP, NamedPipe, MSMQ)
