WCF MessageBodyMember required
I am new to WCF and have a basic question about an attribute [MessageBodyMember]
.
As far as I understand, in the case of the attribute [DataMember]
, if you don't set IsRequired = true, there will be no problem getting and deserializing the message.
What happens if you send a message that is missing MessageBodyMember
s? (For example, from an earlier version of the interface)

If you don't MessageBodyMemberAttribute
have where you explicitly define the contract with MessageContractAttribute
, the message will still be processed with maximum efficiency.
From the MSDN documentation Using Contracts with Messages (under Message Versioning, main focus):
Message bodies have similar versioning rules - both are missing and additional body parts of the message are ignored.
Of course, if your contract (or implementation) is not built to handle the missing body part, then that's a separate issue altogether.
