How to configure message format for a binding in WCF

Question

I found that there are default messaging formats for existing binding types. However, if I need to choose a XML message format in TCP binding, would that be configured in app.config itself?

Answer 1

I suppose WCF supports different message format transports, but however, one should choose a binding corresponding to the message encoding type that is intended to be transported.

On Referring this SO ques , custom web message formats are supported by WebHttpBinding (GET Json etc) and this SO ques refers nettcpbinding to support binary encoded format of XML.

I don't think the message types could be configured in app.config, for eg, a Json type could not be chosen for NetTCPbinding over the config file
