Service Contracts

Service contract

1.Always Apply the ServiceContract attribute on a interface, not a class:

Mark the ServiceContract property on the contract interface, not on the service class

//Avoid:避免
[ServiceContract]
class　MyService
{
[OperationContract]
public　void　MyMethod()
{...}
}
//Correct:正确
[ServiceContract]
interface　IMyContract
{
[OperationContract]
void　MyMethod();
}
class　MyService　:　IMyContract
{
public　void　MyMethod()
{...}
}

2.Prefix the service contract name with an I:

Service contract name begins with I

[ServiceContract]
interface　IMyContract
{...}
