TaskoMask is a free and open-source task management system based on .Net. The primary goal of this project is to be an effort to show how we can design and develop a real software product based on advanced concepts like DDD, TDD, BDD, Microservices, etc. Where the experience of using them in a real product is mostly hidden behind software companies. Please take a look at its wiki!
