Visual Studio Code (VS Code) is a lightweight, extensible code editor that's well-suited for ASP.NET Core development. It supports Git integration, debugging, and offers a wide range of extensions, making it an ideal choice for developers looking for a versatile and customizable development environment.

In ASP.NET Core Identity, developers typically create a custom class, often named "ApplicationUser," which inherits from the built-in IdentityUser class. This custom class is used to add additional properties to the user model, such as user-specific data that your application requires beyond the default user attributes.

When a controller returns a webpage in ASP.NET Core MVC, it typically uses a ViewResult. A ViewResult represents an HTML page that is rendered to the client. It's commonly used to generate HTML views for web applications.

In ASP.NET Core Identity, you create a user with the 'CreateAsync' method. Afterward, you can use the 'AddClaimsAsync' method to associate claims with the user. Claims are often used to store user-specific information or permissions.

The DbSet property in a DbContext represents a collection of entity objects for a specific entity type. It acts as a DbSet that allows you to query, insert, update, and delete records of that entity type in the corresponding database table. It provides a convenient way to work with entities as if they were in-memory objects while abstracting the underlying database operations.

In an ASP.NET Core project, the "bin" folder is specifically designated for storing the compiled output of the application. This folder contains the executable files, libraries, and other artifacts generated during the build process. It's essential for running and deploying the application successfully.

The .NET CLI (Command Line Interface) is a powerful tool for building, running, and managing .NET applications without relying on an integrated development environment (IDE). It allows developers to perform tasks like project creation, compilation, and running applications from the command line, making it an essential tool for command-line enthusiasts and CI/CD pipelines.

In ASP.NET Core, the UrlHelper class provides methods to generate URLs. It allows you to create URLs for different routes and actions in your application. You can access the UrlHelper within your controller or Razor views to generate URLs that point to specific routes or actions.

Razor Pages is a great starting point for creating websites with static pages. It's a lightweight framework in ASP.NET Core designed for creating web pages without the complexities of full MVC. Razor Pages allow you to build simple, static web pages efficiently.

Role-Based Authorization is a key feature of ASP.NET Core Identity that allows you to manage user roles and claims. It enables fine-grained access control by associating users with specific roles and defining role-based policies for authorization.
