Make a Model Class for DBContext to ensure that we will make the tables inside the databases utilizing the code very first migration.
In easy cases as has now been stated this DTO can be employed for binding into the view but in additional sophisticated circumstances it would require the creation of the ViewModel and unloading of data from DTO to ViewModel which is clearly additional operate (when applying MVVM pattern).
This powerful typing makes sure compile-time sort examining, decreasing the chance of runtime faults and producing the codebase extra robust and maintainable.
The Area Model is relevant to the information entry layer of our application. They may be retrieved in the database or persisted into the databases by the information access layer.
As It's a view model so we prefixed the word ViewModel. Although it just isn't necessary to stick to this naming convention, I personally really feel it is good to follow this naming Conference.
Then this kind of well prepared ViewModel is passed to View by controller. How would you physically do it? How can you layout models in an effort to do the small business?

If you wish to examine code regarding how to build a "Baseline" Internet application with ViewModels I can suggest you to down load this code on GitHub: . I made large organization apps.
