Great article.

It is also worth noting that once an assembly is loaded in to SQL Server, the actual DLL file is no longer used because loading an assembly really does load the whole assembly in to SQL Server. Because of this, you can script the assembly just like any other object (in SSMS expand the database, then Programmability, then Assemblies -> right click your assembly and choose "Script Assembly as".

You will end up with a script that contains all the T-SQL required to deploy the assembly to another database (without needing the DLL file), including the encoded binary contents of the assembly itself.

It's pretty handy for deployment to customer databases as you only need to deploy and run a script, not a DLL file and a script.
