Mastering Ninject for Dependency Injection

DI Containers

A DI container is an injector object that injects the dependencies into a dependent object. As we have seen in the previous example, we don't necessarily need a DI container in order to implement Dependency Injection. However, in more complex scenarios, a DI container can save a lot of time and effort by automating most of the tasks that we had to do manually. In real world applications, a single dependant class can have many dependencies, each of which have their own dependencies that forms a large graph of dependencies. A DI container should resolve the dependencies, and this is where the decision of selecting a concrete class for the given abstraction should be made. This decision is made by a mapping table, which is either based ...
