Models in ASP.NET Core MVC Application
A model is a class with .cs (for C#) having both properties and methods. Models are used to set or get the data.
The Model in an MVC application represents the state of the application and any business logic or operations it should perform. Business logic should be encapsulated in the model, along with any implementation logic for persisting the state of the application.
Strongly-typed views typically use ViewModel types designed to contain the data to display on that view. The controller creates and populates these ViewModel instances from the model.
Role of Models in ASP.NET Core MVC Application
The Models in ASP.NET Core MVC Application contain a set of classes that represent the domain data/business data and logic to manage the domain/business data.
In MVC Pattern, The Controllers are used to manage the overall flow of the MVC Application. Models are responsible for storing the data, and these data are used on View.
Views are basically the HTML Pages that get rendered into the browser of the client. In the browser, we generally perform two operations. First, we display the data to the user; second, we get the data from the user. And for both these operations, models are used.
Good Practice
Storing all the Model classes within the Models folder is a good programming practice.
