What steps will reproduce the problem?
1. Create basicHttpBingind WCF Service
2. Use common DTO assembly for data transfer
3. Have service with multiple parameters.
4. Specify first parameter as null, all other parameters become null.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

IConfiguration.cs

    [ServiceContract]
    public interface IConfiguration

    }

    // NOTE: If you change the class name "Configuration" here, you must also update the reference to "Configuration" in Web.config.

This was a interesting bug (some subtle XmlReader nuances). Fixed r469

• Changed state: Fixed

glad I could help, I got around it by just reordering paramaters but I'm happy 
to see it won't be a future issue

May I ask, does this bug impact v1 in any way? (We're 'still' using v1 and we 
cannot switch easily)
