How does a custom SOAP header relate to a custom WCF header?

Question

I am trying to send more info in each message from the client (Mobile Device) to my service. In my research I am finding about interceptors and custom wcf headers.

Now I am starting to see stuff about custom SOAP headers.

What is the difference?

Answer 1

In the end, the result is the same. WCF provides you the option of taking different paths to get there. Using message contracts gives you explicit control over how your messages are shaped and what is contained in the header and the body.

If you already have defined data contracts, then the other approach will allow you to add headers to your existing message structure.
