When a COM server must be created, windows takes a look at HKCR\CLSID\COM Class ID\InprocServer32 (I'm skipping out-of-proc servers deliberately to keep it simple).
The value of this key is used to find the dll containing the implementation (a little simplified, once again).

For managed COM servers this value points to mscoree.dll and only for this type of servers the CodeBase value is neccessary. You can run regedit and then search for "codebase" inside of HKCR\CLSID to see several examples for the required structure of registry entries for managed COM servers.
