HOL SOA21 - WCF Contracts

As mentioned earlier, I am in the process of QA testing some of the Hands On Labs for TechEd 2007. I am currently working on SOA21, which is a very good Windows Communication Foundation (WCF) lab. Unfortunately, it expects the attendee to have a good understanding of .NET 3.0 concepts as well as a good grasp of C#, so it may be somewhat tough for people to get through.

In exercise 2 Task 1, you are asked to rebuild the IMath interface, and you need to ensure that you use the new data contract that was constructed. The complete syntax for this is:

public class MathService : MathTypes.IMath
{
public MathTypes.MathResponse Add(MathTypes.MathRequest req)
{
return new MathTypes.MathResponse(req.x + req.y);
}
}
