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.
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.
If you need to create a real-time communication application, the ________ template of ASP.NET Core is designed for this purpose.
- Real-Time
- WebSockets
- SignalR
- Messaging
The "SignalR" template in ASP.NET Core is specifically designed for creating real-time communication applications. SignalR allows bi-directional communication between the server and clients, making it ideal for applications like chat, online gaming, and live notifications.
What is the primary purpose of a Web API in ASP.NET Core?
- Serve as a user authentication system
- Facilitate communication between web applications
- Manage database schema
- Render web pages
A Web API in ASP.NET Core primarily serves to facilitate communication between web applications. It enables applications to exchange data and functionality over HTTP, making it a crucial component for building RESTful services or supporting AJAX requests in web applications. It does not typically handle user authentication or manage database schemas directly.
In a team development scenario, two developers have created separate migrations for different features at the same time. Before merging these changes into the main branch, what precautions or steps should be taken regarding the Identity migrations?
- Delete one developer's migrations to avoid conflicts
- Ensure both developers use the same database provider
- Collaborate to combine the migrations and resolve conflicts
- Let Entity Framework Core handle the merge automatically
When multiple developers work on separate migrations, it's essential to collaborate and combine the migrations before merging into the main branch. This prevents conflicts and ensures a consistent database schema. Entity Framework Core doesn't handle automatic merge of migrations, so developers need to coordinate their efforts to avoid issues.
In a web application you are developing, you want to ensure that certain middleware only runs for specific routes or URLs. How can you achieve this in ASP.NET Core?
- Use global middleware for all routes
- Configure the middleware in the Startup.cs file
- Use attribute-based routing
- Create separate applications for each middleware
In ASP.NET Core, you can achieve the goal of running certain middleware for specific routes or URLs by using attribute-based routing. By applying attributes to your controller actions or classes, you can specify which middleware should be used for particular routes, providing fine-grained control over middleware execution.
_________ is the lightweight, cross-platform web server used by default with ASP.NET Core.
- Apache
- IIS
- Kestrel
- Nginx
Kestrel is the lightweight, cross-platform web server that is used by default with ASP.NET Core. It's designed for high performance and is well-suited for hosting ASP.NET Core applications. Developers can also use it in combination with reverse proxy servers like Nginx or Apache for production deployments.
