In my Helix based solution, every time I publish a change to a feature project  and load the site I get this error below. 

The error goes away when I publish the website project in the project layer. So every time I publish a feature project in my development box I'm having to republish the website project as well.

Any ideas on how to troubleshoot this? Where is the "code" namespace defined?
