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 Razor, the @functions block allows you to define reusable _________ that can be called multiple times within your view.
- Models
- Variables
- Methods
- Properties
In Razor views, the "@functions" block is used to define reusable C# methods. These methods can be called multiple times within the view, making it a useful feature for encapsulating logic and reducing duplication in your views.
While working on a Razor project, you come across a file named _ViewImports.cshtml. What is the primary role of this file in the Razor view engine?
- It contains the layout definition for all views
- It defines the default content for all views
- It declares the namespaces to be used across all views
- It stores configuration settings for the Razor engine
The primary role of the _ViewImports.cshtml file in the Razor view engine is to declare namespaces to be used across all views. This centralizes namespace configuration, making it easier to maintain and reducing redundancy in individual views.
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.
In the context of ASP.NET Core MVC, where are the business rules and logic typically located?
- View
- Controller
- Model
- Startup.cs
In ASP.NET Core MVC, the business rules and logic are typically located in the Model. The Model represents the application's core logic and data handling, making it the ideal place to implement and enforce business rules. This separation of concerns helps maintain a clean and organized codebase.
You are working on an ASP.NET Core application and need to model a scenario where each Order can have multiple OrderDetails, but each OrderDetail belongs to one Order. How would you model this relationship using Entity Framework Core?
- One-to-Many Relationship
- Many-to-Many Relationship
- One-to-One Relationship
- Self-Referencing Relationship
In this scenario, you should use a One-to-Many Relationship. Each Order can have multiple OrderDetails, creating a parent-child relationship. You can achieve this by defining a navigation property in the Order class pointing to a collection of OrderDetails, and a reference property in the OrderDetail class pointing back to the Order.
To generate a drop-down list in a Razor form, the _______ tag helper can be utilized.
- select
- input
- dropdown
- list
To generate a drop-down list in a Razor form, the select tag helper can be utilized. The select tag helper is used to create HTML select elements and populate them with options, allowing users to choose from a list of predefined values.
You have an ASP.NET Core application where you've defined all your model configurations using data annotations, but now there's a requirement that cannot be achieved using them. How can you handle this model configuration requirement in Entity Framework Core?
- Fluent API Configuration
- Attribute-Based Configuration
- Code-First Approach
- NoSQL Data Store
When data annotations are insufficient for your model configuration needs, you can use Fluent API Configuration in Entity Framework Core. It allows you to define advanced configurations, mappings, and relationships using code-based configuration methods.
