The MVC (Model-View-Controller) folder structure in ASP.NET Core typically includes three main folders: Controllers, Views, and Services. While the Controllers folder contains controller classes, and the Views folder contains the user interface components, the Services folder is where you often place business logic and services that the controllers rely on to perform actions.

When working with ASP.NET Core Identity, user-related data like passwords and email addresses are stored in the "AspNetUsers" table within the database. ASP.NET Core Identity provides a built-in data model and storage mechanism for managing user accounts and authentication.

Microsoft Azure offers a range of services and features specifically tailored for deploying ASP.NET Core applications. These services include Azure App Service, Azure Kubernetes Service (AKS), and Azure Functions, making it a suitable choice for ASP.NET Core development and deployment.

Azure DevOps is a popular DevOps tool that can automate the build, test, and deployment processes for ASP.NET Core applications. It provides a CI/CD pipeline for efficient deployment to various environments. Visual Studio is primarily an IDE, while Notepad++ and Fiddler are unrelated to deployment automation.

When a user submits a form in Razor, the data is usually sent to a/an HTTP POST method in a controller. The HTTP POST method is commonly used for form submissions because it allows data to be sent securely in the request body, and it's designed for actions that modify data on the server.

In an MVC (Model-View-Controller) project, you would typically place business logic or data access logic in Model classes. Models represent the data and business logic of your application, keeping the controller actions focused on handling HTTP requests and the views focused on rendering data. This separation of concerns is a key principle in MVC architecture.

To better organize and prioritize routes in a large-scale application with attribute routing, you can use Route Prefixes. By prefixing routes with common segments, you can group related routes together and reduce the risk of overlapping or conflicting routes. This strategy helps maintain a clear and structured routing system.

In ASP.NET Core, the default layout for Razor views is typically specified in a file named "_Layout.cshtml." This file contains the common HTML structure, including headers, footers, and navigation menus, that will be applied to multiple views in your application.

The RefreshSignInAsync method can be used to refresh the sign-in information of a user in scenarios like role updates or other security-sensitive operations. This method generates a new security token for the user, helping to prevent token-based attacks and ensuring the user's session remains secure.

To ensure that Entity Framework Core doesn't throw detailed database errors to the client, you should use "Exception Handling Middleware." This middleware intercepts exceptions, handles them, and returns a user-friendly error response to the client without exposing sensitive database details.
