Cannot Load Dynamically Generated Serialization Assembly SQLCLR

In article http://support.microsoft.com/kb/913668 it says to generate a serialization assembly and pop this into the database along side the assembly with the serialized type. All well and good, but how doe the XmlSerializer know to look in the database for the assembly - does it use the name of the assembly + XmlSerializer?

It is certainly ambiguous in the aforementioned kb article. In one place it generates an assembly in the database called

CREATE ASSEMBLY [MyTest.XmlSerializers] from
'C:CLRTestMyTestMyTestinDebugMyTest.XmlSerializers.dll'
WITH permission_set = SAFE

and in another it uses

USE dbTest
GO
CREATE ASSEMBLY [MyTest] from 'C:CLRTestMyTest.dll'
GO
CREATE ASSEMBLY [MyTest.XmlSerializers.dll] from 'C:CLRTestMyTest.XmlSerializers.dll'
GO

I can't get either to work, and I've tried various combinations, this and the fact that the kb artice uses two different naming conventions suggests to me that there must be "something else" which links the assembly with the serialization assembly.

Any ideas?

Thanks,

Dan
