Model View Presenter (MVP) Example - #9 Views and Presenters

Video #9 Part 2 of Model View Presenter (MVP) covering Views and Presenters. Visual Studio 2017 development of the Views and Presenters using C# for a demo application begins with this video. WinForms is being used for the graphical user interface. It will take several videos to cover this topic. Note that although WinForms is being used for the user interface, the other parts making up the engine such as service layer and repositories can be reused by other user interface technologies such as WPF which may be demonstrated later in the future.

Note the overview video is in Video #1.

Briefly discussed topics in this Video:

- Creation of Presentation Layer and folders

- Adding Microsoft Unity Container

- Adding graphical images to project resource file

- Creation of support classes in common area

- Early setup of Unity Container in Program.cs demonstrating dependency injection through constructors
