How can you enforce a strict null check in Razor views to catch potential null reference issues at compile-time?
- Use the @ operator
- Add @Nullable attribute to variables
- Use the "as" keyword
- Enable nullable reference types with #nullable directive
To enforce strict null checking in Razor views, you can enable nullable reference types by using the "#nullable" directive at the top of your Razor file. This allows the compiler to detect potential null reference issues at compile-time, reducing runtime errors.
In integration testing for an ASP.NET Core application, what is typically mocked to ensure tests don't affect real data?
- Database
- HTTP Requests
- File System
- Authentication
In integration testing, it's common to mock HTTP requests. This ensures that the tests don't interact with the real database or external services, preventing unintended side effects on actual data during testing.
In which method of the Startup.cs file is routing typically configured in an ASP.NET Core MVC application?
- ConfigureServices
- ConfigureAuthentication
- ConfigureRoutes
- Configure
Routing in an ASP.NET Core MVC application is typically configured in the Configure method of the Startup.cs file. This method sets up the request processing pipeline, including routing rules for different URL patterns.
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.
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 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.
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.
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.
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.
Consider a scenario where you need to return a partial view from your controller. Which action result should you use?
- ViewResult
- PartialViewResult
- ContentResult
- JsonResult
When you want to return a partial view from a controller action, you should use PartialViewResult. This action result is specifically designed to render partial views, allowing you to return a portion of the HTML content to be inserted into a larger view.
How does ASP.NET Core Identity store user data by default?
- In a SQL Server database
- In a NoSQL database
- In plain text files
- In memory
ASP.NET Core Identity, by default, stores user data in a SQL Server database. This includes user profiles, passwords (hashed and salted), and other related data in a structured manner for security and scalability.
What is the primary purpose of routing in ASP.NET Core?
- Handling incoming HTTP requests
- Handling database queries
- Managing server resources
- Managing user authentication
Routing in ASP.NET Core is primarily used for handling incoming HTTP requests and directing them to the appropriate controller and action method. It's essential for determining which code should handle a specific URL or endpoint.
