This is the last one in this current thread for a while :)

By the end of the last example we had code that would discover what stored procs were in a SQL Server database and generate a managed wrapper library that could be extended.

The next step it occured to me was to be then generate an assembly from this source and load it into the currently executing program.  The MSDN pages I have linked to have some good samples.

I'm adding this one to my toolbox of hammers looking for a nail.
