When I build my API in release mode, the following 2 lines cause build time errors that do not occur when I build in debug mode:
using Checkbox.Users;
using Checkbox.Security;

The errors are:
The type or namespace name 'Users' does not exist in the namespace 'Checkbox' (are you missing an assembly reference?)
The type or namespace name 'Security' does not exist in the namespace 'Checkbox' (are you missing an assembly reference?)

Are there any suggestions on how to get this to compile in release mode? Any one else run into this?
