IoC Session Sample Application

This is the sample application for my IoC session at NT conference 2013.

First 5 branches represent different steps in the process of introducing IoC container to an existing project:

  • 0-Start contains the initial project before applying any changes to it.
  • 1-Repository isolates data access by introducing the repository pattern.
  • 2-Interface defines an interface for abstracting the repository.
  • 3-Injection moves the constructor call outside the view model class.
  • 4-Ninject introduces an IoC container to replace manual calling of constructors and satisfying their dependencies.

The remaining branches modify the project to introduce different other features:

  • 5-ServiceLocator replaces IoC container with a service locator class.
  • 6-MemoryRepository refactors the project with a modal editing window and replaces the original repository with one storing data only to memory for the purpose of pointing out service lifetime managemant by IoC containers.
  • 7-SingletonScope reconfigures repository service as a singleton to fix the issue of losing data in the application.
  • 8-Testing adds a sample unit test based on dependency injection principle.

The best way to take a closer look at individual branches is to make a local clone of the repository and switch to the branch you are interested in. If you don't have a Git client installed you can download the source for each of the branches if you click on the Download link and then switch to the Branches tab.
