Overview & Diagram:
The objective of this project was to create a UML diagram to demonstrate the use of interfaces and dependancy injection. This example is an empty framework for a video game engine which can load levels from objects which implement the IWorld interface. Dependancy injection is demonstrated by the constructor for GameEngine which requires the IWorld Implementation to be passed in.
I have also included a sample C# project which I wrote by referencing the diagram. Both the project and executable can be found in the source section below.
