WCF MessageContract Inheritance

Question

I am fairly new to WCF and just have a question on how to correctly get MessageContract inheritance working. A simplified version of my setup is as follows - a \"base\" mess

Answer 1

The error simply wants you to have a default empty contructor that it can use. However, I agree with marc_s; in the projects I've worked on I've rarely used message contract, the only case I can remember was as part of a file transfer service where file chunks were passed in messasges.
