Vista - Questions on DataContract

Questions on DataContract

Hi - a couple of basic questions:

(1)
if I have a custom class as a parameter to an OperationContract method,
does that class need to be a DataContract class?

(2)
do the DataMembers of a DataContract always have to have a "get" and a
"set"?


Thanks,
Peter

Hi!

1) As far as I understand it the classes you expose must be at least serializeable, but the datacontract attribute makes it easy to change the contract later in a compatible way.

Re: Questions on DataContract


1) Custom defined types must have the DataContract attribute. Alternatively,
if you can use MessageContracts.

2) No. They can even be private, protected, or public members but without
having equivalent property declarations.
