Models, Controllers and Views Every have effectively outlined roles and obligations, and they convey amongst each other in very well described approaches. This allows market testability and code reuse.

Since ViewModels are disconnected from the area model, that provides the flexibleness to make use of it the way in which you see in shape.

Among the defining properties from the MVC sample will be the demanding "separation of considerations" it can help enforce amongst the different elements of the application.

This design and style could possibly work… but Let's say we wish to create a website page which will Exhibit a list of orders? The PageTitle, UserName, and ApplicationName Houses will be repeated and develop into unwieldy to operate with.
