Answer 1

The online MSDN documentation is your first source for things like that:

• Read about the ServiceContractAttribute here
• Read about the OperationContractAttribute here
• Read about the DataContractAttribute here

All the MSDN documentation pages contain detailed explanations of all the settings on those contract attributes.
