Move dto error

Hi, 

I have a question at the servicestack forums https://plus.google.com/103997715312012794629/posts/bXV6eKAD5Yg. 
I made these commits to explain my problem.

4a8670f - This commit does not work
7fb613b - This commit works.

The only difference is the namspace of the two files Rockstars.cs and RockstarsResponste.cs. 
How can I make this work when using different namespaces for the service and the DTO's ?
