ServiceCollection

Full source code here. A few weeks ago I wrote a post about using dependency injection to pick between two implementations of an interface. It was a solution I was not very happy with because it meant I had to new up the implementations inside a factory or I had to use service collection to instantiate all implementations of the interface and then use a piece of code to return the one the was wanted.

Full source code here. This is a simplistic approach to the problem and assumes that the dependencies created by the factory do not in turn have their own dependencies. This deficiency could be mediated by passing those dependencies into the factory.
