If all the interface really does is to apply some value. i.e you only set, but not actually get, then the set* functions might be the way to go.

Properties readily provide you with getters, and setters (if var). However, properties are not just that. You can decide what you want to do with the properties in your concrete classes. Delegation, backing field, etc. It all boils down to what it is you really want to achieve

In this particular case of view facade, I think what you really want are methods to expose to your presenter
