The .NET Developer Toolkit

Definition

• Dependency Injection is a pattern
• "ASP.NET Core supports the dependency injection (DI) software design pattern, which is a technique for achieving Inversion of Control (IoC) between classes and their dependencies."
• Repository Pattern: Easy form to change the data base to use in your application
  • Repositories encapsulate data access implementation
  • Decouple implementation / technology from the domain model
  • AppDbContext: EntityFrameworkCore concept. Connect Models with SQL
• DTOs Data Transfer Objects
• Object Mapping
• Docker
  • Containerization platform
  • Build your application into images
  • Run them as containers
  • App Virtualiziation. Not OS Virtualization (VMs)
• CI/CD
  • CI - Continuous Integration
    • Taking code from 1 or more developers, build and testing to ensure that those changes will not break the build
    • Triggered when developers checkin changes to a repository
  • CD - Continuous Delivery
    • Automating release process
    • You can deploy changes 'pressing a button' - Manual
  • CD - Continuous Deployment
    • Code changes will make their way into production, without manual intervention

Extra tools

• Postman
• Docker
• SQL management studio
• GitHub Cli
