Dean Hume - Explicit Interface Usage in C(deanhume.com)

Where possible, I try and program against interfaces as much as possible. I do this because I like Interface-based programming and because I like the characteristics that it brings to the table: reusability, maintainability, and extensibility. It also allows you to effectively test your code using Mocks.
Whether or not you like to code this way, you may however find that there are certain situations in which you need to explicitly set the usage of an interface. When working in a team of developers it is possible that a method on a class could be called using the concrete class instead of an interface. This would break the general interface based concept as a whole and it would also make it a lot harder to find at a later stage.
