When constructing the middleware pipeline in ASP.NET Core, what happens if the next() method isn't called within a middleware component?
- The request processing stops, and no further middleware components are executed.
- The request is redirected to the homepage.
- An exception is thrown, terminating the application.
- The request continues to the next middleware component as usual.
If the next() method isn't called within a middleware component, the request processing stops at that middleware, and no further middleware components in the pipeline are executed. This can lead to incomplete request processing or unexpected behavior in the application.
When setting up a development environment for ASP.NET Core, why might a developer choose Visual Studio Code over Visual Studio?
- Visual Studio Code is free
- Visual Studio Code is open-source
- Visual Studio Code is lighter-weight
- Visual Studio Code has better intellisense
Developers might choose Visual Studio Code over Visual Studio for ASP.NET Core development because it is lighter-weight, making it faster to install and launch. It's also open-source and free, which can be advantageous for those on a budget or who prefer open-source tools. While Visual Studio offers more features for enterprise-level projects, Visual Studio Code is often preferred for smaller projects or when platform independence is a priority.
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.
For configuring and extending the functionalities in ASP.NET Core pipeline, the _______ method is used in the Startup.cs file.
- Configure
- ConfigureServices
- Use
- Add
The Configure method in the Startup.cs file is where you can configure and extend the ASP.NET Core request pipeline. It's where you add middleware and define the order in which they should be executed.
When dealing with file downloads in ASP.NET Core, which action result allows you to send a byte array as the response along with a download dialog to the client?
- FileContentResult
- ObjectResult
- JsonResult
- StatusCodeResult
The FileContentResult action result in ASP.NET Core is used to send a byte array as the response along with a download dialog to the client. It's commonly used for file downloads like PDFs, images, or other binary files. The response content is a byte array, and you can specify the file's content type and download filename.
If you want to create a custom middleware, which method signature should it follow?
- Task InvokeAsync(HttpContext context)
- void Configure(IApplicationBuilder app)
- void Execute(HttpContext context)
- Task Run(HttpContext context)
Custom middleware in ASP.NET Core should follow the Task InvokeAsync(HttpContext context) method signature. This method is called for each HTTP request and allows you to implement your custom logic within the middleware.
During user registration, you notice that users can set very simple passwords like "password123". You want to enforce stricter password rules. Where in ASP.NET Core can you set these rules?
- Startup.cs
- appsettings.json
- Identity Configuration
- ConfigureServices
You can enforce stricter password rules in ASP.NET Core Identity Configuration. In the Identity Configuration, you can customize password requirements such as length, required character types, and more to ensure stronger password policies for your application.
When optimizing ASP.NET Core applications for performance, developers often use the _________ server in conjunction with a reverse proxy.
- Kestrel
- Apache
- Nginx
- Tomcat
When optimizing ASP.NET Core applications for performance, developers often use the Kestrel server in conjunction with a reverse proxy like Nginx or Apache. Kestrel is a lightweight, cross-platform web server optimized for ASP.NET Core, and it's often used as the front-end server while a reverse proxy handles tasks like load balancing and SSL termination.
What does "MVC" stand for in the context of ASP.NET Core?
- Model-View-Controller
- Microsoft Visual Core
- Modern Virtual Computing
- Managed View Component
In ASP.NET Core, "MVC" stands for Model-View-Controller. This architectural pattern separates the application into three main components: the Model (for data and logic), the View (for presentation and UI), and the Controller (for handling user input and managing the flow of data). It helps in building structured and maintainable web applications.
