after droping assembly can still call function

After I drop my assembly I can still execute my UDA, such as:

CREATE ASSEMBLY ASSEMBLY_NAME
authorization [DBO]
from 'c:CLRmyexapmple.dll'
WITH PERMISSION_SET = safe;

then I execute my function


DROP ASSEMBLY ASSEMBLY_MAME
go

I can still execute it now. How come?[:0]

iN REPLY TO MY OWN QUESTION, I had to drop an aggregate first before droping an assembly.
