The @ symbol in a Razor view is used to denote the beginning of ________.
- Code Block
- HTML Tag
- Server-Side Script
- View Component
The @ symbol in a Razor view is used to denote the beginning of server-side script. This script can include C# code that generates dynamic content within the HTML markup, making Razor views a powerful tool for building dynamic web pages in ASP.NET Core.
How can you use Razor forms to send data to an action method via an HTTP GET request instead of the default POST request?
- Use [HttpGet] attribute on the action method
- Use [HttpPost] attribute on the action method
- Use [Route] attribute on the form element
- Use the method attribute on the form tag with the value "GET"
To send data to an action method via an HTTP GET request in Razor forms, you can set the method attribute on the form tag to "GET." This tells the browser to include the form data in the URL as query parameters, allowing you to use [HttpGet] attribute on the action method to receive the data.
What is the primary purpose of the _ViewImports.cshtml file in ASP.NET Core Razor Views?
- Defining shared layout
- Adding HTML elements
- Importing namespaces
- Setting page title
The primary purpose of the _ViewImports.cshtml file is to import namespaces that you want to use across multiple Razor views. This allows you to bring in commonly used classes, extension methods, or helpers without adding individual 'using' directives to each view, promoting maintainability and reducing redundancy.
The dependency injection feature in ASP.NET Core is:
- A built-in container for managing application dependencies
- A third-party library for dependency management
- Not available in ASP.NET Core
- Limited to a specific programming language
ASP.NET Core includes a built-in dependency injection (DI) container for managing application dependencies. This feature helps achieve loose coupling, maintainability, and testability in your code by allowing you to inject dependencies into classes rather than hard-coding them.
What does the Update-Database command do in the context of ASP.NET Core Identity migrations?
- It applies pending migrations to update the database schema.
- It updates the ASP.NET Core Identity framework itself.
- It generates a new migration file for Identity changes.
- It deletes the database and recreates it from scratch.
The Update-Database command, when used with Identity migrations, applies any pending migrations to update the database schema to match the current state of your Identity models. This ensures that the database structure aligns with your Identity-related code changes.
How does the ASP.NET Core Identity system handle migrations in a distributed deployment scenario where multiple instances might attempt to apply migrations simultaneously?
- It uses a distributed lock to ensure only one instance applies migrations
- It allows all instances to apply migrations concurrently
- It relies on database transactions for synchronization
- It doesn't support distributed deployments
In a distributed deployment scenario, ASP.NET Core Identity uses a distributed lock mechanism to ensure that only one instance applies migrations at a time. This prevents conflicts and ensures database consistency. Allowing multiple instances to apply migrations concurrently could lead to issues such as data corruption or race conditions. While database transactions are used for consistency, they may not be sufficient for distributed deployments. ASP.NET Core Identity is designed to support distributed scenarios.
Your team lead mentions the use of a "_Layout.cshtml" file in your ASP.NET Core project. What is the primary role of this file?
- Defining the webpage's structure and common elements
- Storing application configuration settings
- Handling user authentication
- Rendering JavaScript code
The primary role of "_Layout.cshtml" in ASP.NET Core is to define the webpage's structure and common elements, such as the header, footer, and navigation menu. It allows for consistent layout across multiple pages in your application.
Which tool would you use for building, running, and managing .NET applications without an IDE?
- .NET CLI
- Visual Studio
- Visual Studio Code
- ReSharper
The .NET CLI (Command-Line Interface) is a powerful tool for building, running, and managing .NET applications without relying on a full-fledged Integrated Development Environment (IDE). It allows developers to work efficiently in the command-line environment, making it a versatile choice for various .NET development tasks.
When leveraging the power of client-side validation in Razor forms, the unobtrusive _________ validation library is often used in conjunction with jQuery.
- Ajax
- Validation
- Unobtrusive
- jQuery
When using client-side validation in Razor forms, the unobtrusive Validation library is frequently used in conjunction with jQuery. This library allows you to define validation rules for form fields on the client side, providing immediate feedback to users without requiring a server round-trip. It's a crucial component for building responsive and user-friendly web applications.
How do Razor tag helpers differ from HTML helpers in ASP.NET Core?
- They are written in C#
- They use HTML-like syntax
- They are used for validation
- They are not used for forms
Razor tag helpers in ASP.NET Core use HTML-like syntax, making them more natural and readable in Razor views. HTML helpers typically involve writing C# code within the view, which can be less intuitive for front-end developers.
