Dependency injection in ASP.NET Core MVC allows services to be injected into controllers via their _________.
- Constructors
- Properties
- Methods
- Fields
Dependency injection in ASP.NET Core MVC allows services to be injected into controllers via their constructors. This approach promotes the use of constructor injection for better testability and maintainability of your controllers, ensuring that required services are provided when the controller is created.
In scenarios with table splitting in Entity Framework Core, how is it ensured that multiple entities map to a single table?
- Using the .ToTable() method with the same table name
- Manually specifying the same columns for multiple entities
- Table splitting doesn't allow multiple entities in one table
- By using the .MapToStoredProcedures() method
To ensure that multiple entities map to a single table in table splitting scenarios, you can use the .ToTable() method with the same table name for both entities. This tells Entity Framework Core to store both entities in the same table in the database.
What is the primary purpose of Razor views in ASP.NET Core?
- Defining database models
- Handling HTTP requests
- Creating user interfaces
- Managing server configurations
Razor views in ASP.NET Core are primarily used for creating user interfaces. They allow developers to define the structure and layout of web pages by mixing HTML markup with C# or VB.NET code. Razor views enable dynamic content rendering and help build the presentation layer of web applications.
What is a primary advantage of using ASP.NET Core Identity over custom authentication systems?
- Built-in Security Features
- Lower Development Cost
- Greater Flexibility
- Faster Performance
One of the primary advantages of using ASP.NET Core Identity is its built-in security features. It handles common security concerns like password hashing, account lockout, and two-factor authentication, saving developers from implementing these features manually. This enhances application security.
To ensure all necessary packages and dependencies are up-to-date in an ASP.NET Core project, you'd typically run the dotnet _________ command.
- upgrade
- update
- restore
- clean
To ensure all necessary packages and dependencies are up-to-date in an ASP.NET Core project, you'd typically run the dotnet update command. This command checks for newer versions of packages and updates them in the project file. It helps maintain the project's dependencies and keeps it compatible with the latest libraries and features.
What is the primary role of the "View" in the MVC design pattern?
- Handling User Input
- Displaying Data
- Managing Application Logic
- Routing Requests
The primary role of the "View" in the MVC design pattern is to display data to the user. It is responsible for presenting information in a user-friendly manner and does not handle user input or application logic. Instead, it relies on the "Controller" to provide the data to be displayed.
While running your suite of unit tests, you notice that one test fails intermittently. What could be a potential reason for such a flaky test in a unit testing context?
- External Dependencies
- Lack of Isolation
- Test Order Dependency
- Unhandled Exceptions
A flaky test in a unit testing context might be due to "Test Order Dependency." If the order in which unit tests run affects their outcomes, it can lead to intermittent failures. Unit tests should be independent and not rely on the execution order.
In your ASP.NET Core application, you notice that some middleware is not executing as expected. Considering the middleware pipeline, what could be the potential reason?
- The middleware order is incorrect.
- The application is not running on a supported OS.
- The middleware is not properly configured.
- The server is overloaded.
In the ASP.NET Core middleware pipeline, the order in which middleware components are added matters. If the middleware order is incorrect, it can lead to unexpected behavior. Middleware components are executed in the order they are added to the pipeline.
Which ASP.NET Core feature allows you to implement authentication and authorization logic to protect your Web APIs?
- Dependency Injection
- Middleware
- Entity Framework Core
- Identity
Identity is an ASP.NET Core feature that allows you to implement authentication and authorization logic to secure your Web APIs. It provides user management, role-based access control, and authentication mechanisms like JWT (JSON Web Tokens) out of the box. Developers can easily integrate Identity into their ASP.NET Core applications to manage user authentication and authorization requirements.
You're developing a multi-page ASP.NET Core application. For most pages, you want to use the same header and footer, but for a few pages, you want a different header. How would you best accomplish this with Razor Views?
- Create a custom layout for pages with different headers.
- Use conditional statements in the Razor layout to determine which header to display.
- Create separate views for pages with different headers.
- Modify the _Layout.cshtml file for each page.
To achieve different headers for specific pages in an ASP.NET Core application, you can create a custom layout for those pages. This approach allows you to maintain a consistent structure while customizing headers for specific pages.
