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.
What is the primary advantage of using ASP.NET Core Identity for user management in your web application?
- Simplified User Authentication
- Faster Page Load Times
- Enhanced UI Design
- Improved SEO Ranking
ASP.NET Core Identity offers a comprehensive solution for user authentication and management. Its primary advantage lies in providing simplified user authentication, allowing developers to focus on building features rather than reinventing user management functionalities. It includes features like user registration, login, password reset, and role-based authorization out of the box.
A new developer joins your team and is unfamiliar with the structure of ASP.NET Core projects. They ask you where the core application logic, such as controllers and models, resides. What would be your response?
- Controllers are in the "Views" folder, and models are in the "Controllers" folder.
- Controllers are in the "Models" folder, and models are in the "Views" folder.
- Controllers are in the "Controllers" folder, and models are in the "Models" folder.
- Controllers and models are both in the root directory.
In ASP.NET Core, the core application logic is typically organized as follows: Controllers are in the "Controllers" folder, and models are in the "Models" folder. This structure helps maintain a clean separation of concerns and follows the convention over configuration (CoC) principle.
In a tutorial, you see a Razor form with the attribute asp-controller="Home". What does this attribute indicate?
- The name of the submit button
- The HTML form method
- The name of the controller handling the form
- The CSS class of the form
The asp-controller attribute in a Razor form indicates the name of the controller that will handle the form submission. This attribute is part of the Razor Pages and MVC conventions in ASP.NET Core, helping to route the form data to the appropriate controller action.
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.
Your college project involves creating a simple blog. Which ASP.NET Core template provides functionalities like user comments and posts out of the box?
- Web API
- Empty
- MVC
- Blazor
The ASP.NET Core MVC template is ideal for creating a simple blog. It provides built-in features for handling user comments and posts. MVC (Model-View-Controller) is a pattern that separates the application into components for managing data, the user interface, and the control flow, making it suitable for this scenario.
Which component of the ASP.NET Core development environment allows for dependency resolution and package management?
- .NET Compiler
- NuGet Package Manager
- ASP.NET Core Runtime
- Entity Framework Core
The NuGet Package Manager is the component of the ASP.NET Core development environment that handles dependency resolution and package management. It is a powerful package manager that helps developers manage and integrate third-party libraries and packages seamlessly into ASP.NET Core projects.
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.
