In which folder are Razor views typically stored in an ASP.NET Core MVC project?
- Models
- Controllers
- Views
- Middleware
Razor views in an ASP.NET Core MVC project are typically stored in the "Views" folder. This folder structure follows the convention-over-configuration principle, making it easy to locate and organize view files.
How do Razor Tag Helpers enhance the HTML markup in Razor views?
- They add JavaScript functionality
- They create custom HTML elements
- They improve the performance of web applications
- They provide a more readable and maintainable way to generate HTML
Razor Tag Helpers enhance the HTML markup in Razor views by providing a more readable and maintainable way to generate HTML. They abstract complex HTML and server-side logic, making it easier to work with HTML elements and attributes while keeping your code clean and organized.
You're tasked with creating a layout that has an optional sidebar. Only specific views will provide content for this sidebar, while others won't. How would you design this in the Razor layout?
- Use sections in the Razor layout to define the sidebar content, and individual views can choose to fill the sidebar section or leave it empty.
- Create separate layouts for views with and without a sidebar.
- Use JavaScript to conditionally load the sidebar content in the client-side code.
- Use a global variable to toggle the sidebar's visibility in all views.
To create a layout with an optional sidebar in ASP.NET Core using Razor, you can use sections in the layout to define the sidebar content. Individual views can then choose to fill the sidebar section or leave it empty, allowing for flexibility in displaying the sidebar based on specific view requirements.
How can you set a default document (like index.html) to be served when the user accesses the root URL in an ASP.NET Core app?
- Use the app.UseDefaultDocument() method
- Configure the DefaultDocument property in Startup.cs
- Add a default.html file to the project
- Use the app.UseIndexFile() method
To set a default document like index.html to be served when the user accesses the root URL in an ASP.NET Core app, you can configure the DefaultDocument property in Startup.cs. This allows you to specify the default file that should be served when a directory is requested without a specific file name.
You're tasked with creating a middleware that logs every incoming request's User-Agent header. Which approach would you take to capture this data in ASP.NET Core?
- Using UseMiddleware extension method
- Implementing a custom middleware class
- Utilizing a filter attribute
- Directly modifying the ASP.NET Core pipeline
To capture the User-Agent header in ASP.NET Core, you would create a custom middleware class that intercepts incoming requests. This middleware class can access the request headers and log the User-Agent information as needed. The UseMiddleware extension method is used to add custom middleware components to the pipeline.
In what scenario would you need to manually set the name attribute of an input field in a Razor form, despite using model binding?
- When using complex model hierarchies
- When applying client-side validation
- When using tag helpers
- When handling file uploads
You may need to manually set the name attribute of an input field in a Razor form when dealing with complex model hierarchies. Model binding can sometimes generate complex names that may not match your desired structure, so manually setting the name attribute ensures proper binding in such cases.
During development, you notice that accessing a related entity property causes an additional query to the database. This was not the intended behavior, and you wish to load related data upfront. Which loading strategy should you employ?
- Lazy Loading
- Eager Loading
- Explicit Loading
- No Loading
To load related data upfront and avoid additional queries, you should employ "Eager Loading." Eager Loading allows you to retrieve related entities in a single query by specifying what related data to include using the Include method in Entity Framework Core.
You've been given a design for a registration page that contains fields like username, password, and email. Which tool or feature in ASP.NET Core will help you create a corresponding backend model for this design?
- Entity Framework Core
- Razor Pages
- ASP.NET Core Identity
- ASP.NET Core Middleware
To create a corresponding backend model for the registration page, you can use Entity Framework Core. Entity Framework Core allows you to define data models that represent database tables, making it easier to work with data in your ASP.NET Core application.
How does the order of route definitions impact the routing process?
- The order has no impact
- Routes are executed in a random order
- Routes are executed in the order they are defined
- Routes are executed alphabetically
In ASP.NET Core, the order of route definitions significantly impacts the routing process. Routes are executed in the order they are defined, and the first matching route is used to handle the request. This allows developers to control how different routes are prioritized and which controller action or endpoint is invoked based on the request URL.
What is the primary purpose of Razor views in ASP.NET Core?
- Define the routing logic
- Generate JavaScript code
- Create user interfaces
- Manage server configurations
Razor views in ASP.NET Core are primarily used for creating user interfaces for web applications. They allow developers to define the structure and layout of web pages using a combination of HTML and C# code. Razor views are essential for rendering dynamic content and interacting with server-side data in web applications.
When you're creating a project for microservices, the ________ template in ASP.NET Core might be a suitable choice.
- Microservices
- Web API
- Desktop
- Cloud
The "Web API" template in ASP.NET Core is well-suited for building microservices. Microservices often require building lightweight APIs to interact with other services, and the "Web API" template provides the necessary tools and framework for this purpose.
During a code review, you notice that a developer placed images directly in the root directory of an ASP.NET Core project. What recommendation would you give to correctly organize these static files?
- Leave them in the root directory for performance reasons.
- Move them to a folder named "Images" in the root directory.
- Embed the images directly into the Razor views.
- Create a new project just for storing images.
To maintain a well-organized ASP.NET Core project, it's advisable to move static files like images to specific folders. Placing them in a folder named "Images" in the root directory is a common practice. This improves project organization, makes it easier to locate assets, and adheres to best practices for structuring web projects.
