Two aspects

Security has two aspects: Authentication and Authorization

Notes

  • In the article A4.03 we mentioned permission storage.
    • Except that, we need the User interface for managing user data. To generate the Typescript classes we need the View-declarations.
      • Again, we can define Views only after declaring Entities and DBContext.
      • Thus, before creating views, we need a temporary explicit declaration of some entities defined by Microsoft IdentityDbContext. After generating the Views we must delete temporary entities.
      • Another aspect is permission storage entities. Some of permission storage entities must reference role-entity to persist (permission bitmask, role) pairs.
  • As a result, we need to generate Entities and DBContext twice.
    • first time, for modeling
    • second time, for production
  • In this article we will show how to generate Entities and DBContext for modeling.
    • Next time, after creating the code for the Views, we will regenerate the Entities and DBContext for production.
