While setting up an ASP.NET Core project, you want to ensure that your application can serve images and other static files. Which middleware should you configure?
- Authentication Middleware
- Static File Middleware
- Logging Middleware
- Routing Middleware
To serve static files like images, CSS, and JavaScript in an ASP.NET Core application, you should configure the Static File Middleware. This middleware allows you to serve files from specific directories in your project, enhancing the performance of your web application.
What is the primary goal of unit testing in software development?
- To find all bugs in the software
- To ensure the user interface is intuitive
- To verify that individual components work as expected
- To test the entire system's functionality
Unit testing primarily aims to verify that individual components (units) of a software application work correctly in isolation. It's not focused on finding all bugs in the software or testing the complete system's functionality, which is the role of integration and system testing.
Which ASP.NET Core method is used to return a Razor view from a controller action?
- ViewResult
- JsonResult
- ContentResult
- RedirectResult
The ViewResult is used to return a Razor view from a controller action in ASP.NET Core. It allows you to render a view and pass a model to it, which can then be used for dynamic content generation.
You are building a real-time dashboard which updates the user interface as soon as data changes on the server. Which technology in the ASP.NET Core ecosystem would be most suitable for this?
- SignalR
- WebSocket
- WebSockets API
- AJAX
SignalR is a library in ASP.NET Core designed specifically for real-time web applications. It allows server-to-client and client-to-server communication over various transport protocols, making it an ideal choice for real-time dashboards. SignalR abstracts away the complexities of WebSocket and other transport protocols, simplifying real-time communication.
The Fluent API provides more configuration options compared to data annotations and is configured in the _________ method of the DbContext.
- OnModelCreating
- ConfigureOptions
- DbContextSetup
- ModelOptions
The Fluent API in Entity Framework Core provides advanced configuration options for defining the database schema and behavior of your entities. It is configured in the OnModelCreating method of the DbContext class. Using the Fluent API, you can customize table names, define composite keys, configure relationships, and perform various other advanced configurations that may not be possible with data annotations alone.
In a large application with numerous controllers and actions, you're noticing performance issues related to route matching. What can you implement to optimize the routing performance?
- Use attribute routing
- Implement custom route constraints
- Use wildcard routes
- Implement route caching
To optimize routing performance in a large application, you can implement route caching. Route caching stores the results of route matching so that subsequent requests with the same URL can be quickly resolved without re-evaluating the route templates. This can significantly improve performance in large applications with complex routing configurations.
How does the ASP.NET Core MVC framework differentiate between different action methods when they have the same name but different HTTP verbs (e.g., GET vs. POST)?
- By their parameter types
- By their route attributes
- By their method names
- By their controller names
In ASP.NET Core MVC, the framework differentiates between actions with the same name but different HTTP verbs based on their route attributes. These attributes define the URL patterns that map to specific action methods, allowing the framework to route requests correctly.
In ASP.NET Core Identity, the _________ property is often used to ensure unique user identification beyond just the username.
- PhoneNumber
- SecurityStamp
- Role
In ASP.NET Core Identity, the SecurityStamp property is often used to ensure unique user identification beyond just the username. The security stamp is a unique value associated with each user, and it can be used to invalidate user sessions and tokens when security-related changes occur, such as password changes or logouts.
The ASP.NET Core "Web Application" template is best suited for creating ________-based applications.
- Web
- Mobile
- Desktop
- Cloud
The "Web Application" template in ASP.NET Core is designed for creating web-based applications. It provides the necessary structure, libraries, and tools to build web applications that can run on various platforms and browsers.
What is the primary goal of unit testing in ASP.NET Core projects?
- To validate the overall functionality of the application
- To test the entire application as a whole
- To ensure that each component or unit of code works correctly in isolation
- To test only the user interface
Unit testing in ASP.NET Core projects focuses on testing individual components or units of code in isolation. The primary goal is to ensure that each unit functions correctly and meets its specific requirements. This helps in identifying and fixing bugs early in the development process, contributing to the overall stability and reliability of the application.
