Legacy code can be awkward to work with. Technology is progressing so fast that things worked with just few years ago are now out of date. The project that my team works on was primarily written in ASP.NET MVC with DevExpress Web Controls and EDMX Database-first approach. We decided to refresh it, clean up the underlying architecture, and migrate it with the view layer to React.

EXAMPLE PROJECT  I’ve created a simple React project in TypeScript for this article. The interesting points here are:   IoC initialization NameProvider class (which will provide a…
