Everyone and his mother nowadays is charmed by DDD, but it's so easy to couple yourself into the mermaid song of a framework... At ofertix.com we are refactoring our codebase following the DDD principles while fighting against our beloved Symfony for some space, like a marriage. So the talk would drive from basic DDD principles to how easy is to couple yourself into the framework, then how to prevent the framework to taint the domain layer and finally how to put it at the service of the application.
