Gradually, I understand semantics is the driven force of the evolution of software tools, framework, platform, methodologies and standards. As a .net developer, I use the object-oriented programming, domain driven development, agile programing, mocking framework, asp.net mvc, css, xhtml, wpf, RESTful web service.
