When defining an attribute route, which of the following attributes would you use to specify a route for an action method?
- [Route]
- [Action]
- [Controller]
- [HttpGet]
To specify a route for an action method using attribute routing in ASP.NET Core, you would use the [Route] attribute. This attribute allows you to define the URL pattern that maps to the action method, giving you fine-grained control over routing behavior.
A _________ in a DbContext represents a collection of entities that can be queried from the database.
- DbSet
- EntitySet
- EntityCollection
- EntityList
In Entity Framework Core, a DbSet in a DbContext represents a collection of entities that can be queried from the database. Each DbSet corresponds to a table in the database, and you can use LINQ queries to retrieve data from and manipulate data in these collections. The DbSet is a fundamental concept in Entity Framework Core and serves as the entry point for interacting with database entities.
What is the main difference between [Authorize] and [AllowAnonymous] attributes?
- [Authorize] allows access only to authenticated users, while [AllowAnonymous] allows access to all users.
- [Authorize] allows access to all users, while [AllowAnonymous] allows access only to authenticated users.
- [Authorize] is used for authentication, while [AllowAnonymous] is used for authorization.
- [AllowAnonymous] is used for authentication, while [Authorize] is used for authorization.
The main difference is that [Authorize] restricts access to authenticated users by default, whereas [AllowAnonymous] allows access to all users regardless of their authentication status. [Authorize] is primarily for authentication, and [AllowAnonymous] is for allowing access without authentication.
When working with Identity migrations, what happens if there's a conflict between two migrations?
- A migration error occurs, and you must resolve it manually.
- The migrations are applied sequentially without any issues.
- The conflicting migrations are merged automatically.
- ASP.NET Core doesn't support conflicting migrations in Identity.
In case of a conflict between two Identity migrations, a migration error occurs, and it must be resolved manually by the developer. Conflicts can arise when two migrations attempt to modify the same Identity-related tables or data.
ASP.NET Core supports the dependency injection design pattern. The __________ method in the Startup.cs file is used to configure services for this purpose.
- ConfigureServices
- Configure
- AddServices
- RegisterServices
In ASP.NET Core, the ConfigureServices method in the Startup.cs file is used to configure services, including registering dependencies for dependency injection. This method allows you to configure how various parts of your application should interact and obtain the services they need.
In an e-commerce application, you have a controller that manages orders, and it is protected using the [Authorize] attribute. However, you wish to allow a public tracking feature where users can see the status of their order without logging in. How would you implement this?
- Create a separate controller or action without the [Authorize] attribute for public order tracking.
- Use client-side authentication to allow access to order tracking.
- Use a cookie-based authentication mechanism for order tracking.
- Allow anonymous access to the entire order controller.
To implement a public order tracking feature, you should create a separate controller or action without the [Authorize] attribute. This allows unauthenticated users to access order tracking while keeping the rest of the order management secure with authentication.
In ASP.NET Core, if you want to serve static files like images, CSS, and JavaScript, you need to add the _________ middleware.
- StaticFile
- FileServer
- ContentDelivery
- StaticContent
To serve static files like images, CSS, and JavaScript in ASP.NET Core, you need to add the StaticFile middleware. This middleware enables your application to serve these files efficiently without needing to write custom code for each file request. It's essential for building web applications with static assets.
You want to use a database with your ASP.NET Core web application. Which ORM (Object-Relational Mapping) framework is natively supported by ASP.NET Core for this purpose?
- Entity Framework Core
- Hibernate
- SQLAlchemy
- Doctrine
Entity Framework Core (EF Core) is the ORM framework natively supported by ASP.NET Core. It simplifies database access by allowing developers to work with databases using C# objects, making it a popular choice for database interaction in ASP.NET Core applications.
What is the role of the "wwwroot" directory in an ASP.NET Core project?
- It contains configuration files for the project.
- It stores static web assets such as HTML, CSS, and JavaScript files accessible to the client-side of the application.
- It houses database connection strings.
- It stores server-side code files.
The "wwwroot" directory in an ASP.NET Core project serves as the location for static web assets that can be directly accessed by clients. These assets include HTML, CSS, JavaScript files, images, and other client-side resources. Placing them here ensures that they are publicly available without needing special routing or controller actions.
You've heard about two-factor authentication for enhancing security. How can ASP.NET Core Identity help in implementing this feature?
- Built-in Support for Two-Factor Authentication
- Seamless Integration with Third-Party APIs
- Automatic Firewall Configuration
- Enhanced Database Encryption
ASP.NET Core Identity simplifies the implementation of two-factor authentication by offering built-in support. This means that developers can easily enable and configure two-factor authentication for user accounts within their applications, adding an extra layer of security through methods like SMS codes or authenticator apps.
