Attention problems in the use of namespace in Unity3d

Recent refactoring in the game of the same logic, but also to add new functional logic, because of the various naming problems, using namespace to control.
However, the use of namespace in the Unity3d engine is different from the general one, which needs to be noted:
The script to be a component component cannot be placed under namespace because the script name of the component is the same as the class name (that is, Xxxx.cs is consistent with xxxx:monobehaviour), and if the latter is placed under namespace, Unity3d at compile time, will not be able to identify the cause of the warning, while running on the PC may not error, but sent to the phone runtime (APK) will be a problem.
