For extra crazy fun, attach extension methods to an Interface. Then you can reference that Interface in multiple Classes, and have access to the extension methods in each. A little hack for when you *really* wanted to use multiple inheritance in C# ;)

what are the differences or benefits of using extension methods vs inject dependency ?

[darrabam]

Nice, is there something similar for attributes? I often find myself inheriting framework classes just to add few extra attributes
