• On Insert run method A
• On Update run method B
• On Delete run method C

I could manually add this in a controller but I'd rather a more concrete solution, the desired effect is that no method can insert into the table without also inserting into the audit log.

This project shows how you can add pre- and post-action hooks into an Entity Framework 4.1 DbContext. You can either extend its HooksDbContext class or see how it implements the hooks in the code and change it to suit your purposes.
