The [FromRoute] attribute is used to bind a route parameter to an action method parameter in ASP.NET Core. If you want to enforce that the parameter should be of a specific type, like integer, you can add the appropriate data type constraint in your action method's parameter using C# data type annotations.

In the context of older versions of ASP.NET, "Master Pages" were used to define a consistent layout for web pages. They allowed developers to create a template or master layout that contained the common structure and elements shared by multiple pages, similar to Razor Layout Views in ASP.NET Core. Master Pages helped maintain a uniform appearance across a website.

The "Worker Service" template in ASP.NET Core is tailored for background processing tasks, such as scheduled jobs, message processing, and other non-HTTP tasks. It doesn't include the typical web application features like HTTP endpoints, controllers, or views, making it ideal for scenarios where you don't need to handle HTTP requests.

The appsettings.json file in an ASP.NET Core project typically contains project metadata, package dependencies, and project-specific settings. It's a JSON configuration file used to store various configuration values for the application, such as database connection strings, logging settings, and custom application settings. This separation of configuration from code promotes flexibility and maintainability in ASP.NET Core applications.

Kestrel is a distinctive component in the ASP.NET Core ecosystem because it's a cross-platform, lightweight, and high-performance web server. Unlike some other web servers that are platform-specific, Kestrel can run on Windows, Linux, and macOS, making it a preferred choice for ASP.NET Core hosting. It is often used in combination with reverse proxy servers like Nginx or IIS for production scenarios.

Implementing email confirmation in ASP.NET Core Identity involves several steps. You need to configure an email service, update the Startup.cs to include email settings, send a confirmation link to the user's email, and add a ConfirmEmailAsync method to confirm the email address when the link is clicked.

In ASP.NET Core, the 'wwwroot' folder is the default location for storing static web assets like images, scripts, and CSS files. These assets can be directly served to clients without the need for additional routing.

To restrict a controller action to users with the "Admin" role, you should use the [Authorize(Roles = "Admin")] attribute. This attribute ensures that only users with the specified role can access the action.

The correct option is @Html.BeginForm. This Razor helper is used to generate the opening

element in an ASP.NET Core view when you want to create a form for user input. It sets the action and method attributes of the form, allowing you to specify where the form data should be submitted and how it should be sent (GET or POST).

To enforce stricter password policies in ASP.NET Core, you can configure Identity Options. ASP.NET Core Identity provides built-in password policies that you can customize to require stronger passwords. You can define password complexity rules, including minimum length, required characters, and more in the Identity Options configuration.
