This potent typing makes sure compile-time form checking, minimizing the chance of runtime errors and building the codebase more robust and maintainable.

Due to the fact ViewModels are disconnected with the area model, that gives the flexibility to use it the way the thing is in shape.

One example is, to assist the situation exactly where we wish to change the "Country" textbox within our Edit view from remaining an HTML textbox to your dropdownlist, we are able to update our Edit() motion system to pass (in addition to a Evening meal object) a SelectList item that may be used as being the model of a "International locations" dropdownlist.
Working with ViewModels in MVC for finer granularity and much better SoC results in a lot more very easily maintainable and testable code. Don't forget, unit testing is about testing modest models
Together with improved coding methods, there are plenty of organization reasons demonstrating why you could possibly think about using ViewModels:
An information Transfer Object (DTO) is a category with Qualities that match a desk schema within a databases. DTOs are named for their popular use for shuttling facts to and from a data retail store.
