Can''t drop trigger assembly

Created an assembly based on this article...

http://sqljunkies.com/Article/4CD01686-5178-490C-A90A-5AEEF5E35915.scuk

Now I want to make changes and redeploy the assembly but when I try to drop I get this.

IF EXISTS (SELECT * FROM sys.assemblies asms WHERE asms.name = N'AuditCommon')

DROP ASSEMBLY [AuditCommon]

Msg 6590, Level 16, State 1, Line 3

DROP ASSEMBLY failed because 'AuditCommon' is referenced by object 'clr_trigger'.

Any ideas?

Figured it out. clr_trigger was a trigger that I created somewhere along the way which was dependent upon the assembly. It didn't appear anywhere in SQL Manager Studio so I thought that it was some sort of system object.|||A late reply,

using show dependencies, list out those need to removed. Remove the listed first and then drop the assembly.
