Usage of non-extensible code is not recommended, which Telligent.Evolution.Components.ApplicationType and Telligent.Evolution.Components.ApplicationConfiguration both are, in addition to our internal service binding infrastructure. I'd recommend you check out the Developer Training on creating custom Application types: Creating Custom Applications and Content 
 Regarding service bindings, I'd recommend checking out the training on Dependency Injection here: Dependency Injection
