In the MVC (Model-View-Controller) pattern, the Model component is responsible for managing the application's data and business logic. In this scenario, it would be responsible for fetching the product details from the database. The Model interacts with the database and provides data to the Controller, which then passes it to the View for rendering.

To quickly scaffold a new ASP.NET Core controller, a developer would use the dotnet new controller CLI command. This command generates the necessary files and code structure for a controller, making it a time-saving tool for building web APIs and MVC applications.

The UseMvc method in Startup.cs is used to configure routing for the ASP.NET Core MVC framework. It sets up how incoming HTTP requests are mapped to controller actions, allowing you to define the URL structure and route parameters. This is crucial for handling requests and directing them to the appropriate controllers and actions.

In a Razor Layout View, you can make sections optional by checking if the section is defined using @if (IsSectionDefined("Optional")). This way, the section will only be rendered if it's defined in the child view. The other options are not valid approaches for making sections optional.

To perform command-line tasks in ASP.NET Core projects, you should ensure that the .NET CLI (Command Line Interface) is installed. It provides a set of commands for building, running, testing, and publishing ASP.NET Core applications.

A server error caused by an unhandled exception in a web application is commonly associated with the HTTP status code 500 - Internal Server Error. This code indicates that an unexpected error occurred on the server, and it's a general indicator of a problem on the server side.

The @ViewData object is a type of Dictionary in ASP.NET Core. It is used to pass data from the controller to the view. ViewData allows you to share data between different parts of your application, making it available for rendering in the view.

The primary difference between the Process and ProcessAsync methods in custom Tag Helpers is that Process is synchronous, while ProcessAsync is asynchronous. Process is used for synchronous processing and tag rendering, whereas ProcessAsync is employed for asynchronous operations, such as waiting for external data or I/O operations, which is important for responsiveness in modern web applications.

To restrict access to specific pages for the "Admin" role, you should use the [Authorize(Roles = "Admin")] attribute. This attribute allows only users with the "Admin" role to access the decorated controller or action method.

ASP.NET Core Identity is a framework for user authentication and authorization. It provides robust features for managing user identities, including user registration, login, and role-based access control, making it an essential component for securing ASP.NET Core applications.
