The Output property of a custom tag helper, of type _______, allows you to manipulate the final output of the tag helper.
- string
- int
- TagHelperContent

How can you conditionally branch the middleware pipeline based on specific criteria, like a request path or a header value?
- Use conditional statements within middleware
- Add custom middleware for branching
- Utilize the UseWhen method
- Modify the request object directly
To conditionally branch the middleware pipeline, you can use the UseWhen method provided by ASP.NET Core. This method allows you to specify a condition, and based on that condition, you can choose whether to execute certain middleware components or not. It's a powerful way to customize the pipeline based on specific criteria.
In complex scenarios, instead of using simple roles or claims, you might need a custom authorization policy. How do you apply a custom policy using the [Authorize] attribute?
- [Authorize(Policy = "CustomPolicy")]
- [Authorize("CustomPolicy")]
- [Authorize(CustomPolicy)]
- [Authorize(Roles = "CustomPolicy")]
To apply a custom authorization policy using the [Authorize] attribute, you should use the syntax [Authorize(Policy = "CustomPolicy")]. This tells ASP.NET Core to use the "CustomPolicy" when authorizing access to the action or controller.
When you want to use a namespace across multiple Razor views without adding it to each view, where should you define it?
- In the _ViewStart.cshtml file
- In the _Layout.cshtml file
- In the _ViewImports.cshtml file
- In each individual Razor view
You should define a namespace that you want to use across multiple Razor views in the _ViewImports.cshtml file. This file is specifically designed to consolidate 'using' directives, making them accessible throughout the views that share it, thereby improving code organization and reusability.
In ASP.NET MVC, Master Pages have been replaced with _______ in Razor views.
- Partial Views
- Layout Pages
- Helper Pages
- Include Pages
In ASP.NET Core Razor views, Master Pages have been replaced with "Layout Pages." Layout Pages define the overall structure and common elements for views, similar to Master Pages in previous versions of ASP.NET. They provide a consistent layout for multiple views within your application.
You're new to ASP.NET Core and are confused about where to specify the common design elements (like headers and footers) that appear on every page. Which Razor concept should you explore for this purpose?
- ViewComponents
- Razor Layouts
- Partial Views
- Tag Helpers
To specify common design elements like headers and footers that appear on every page, you should explore Razor Layouts. Razor Layouts allow you to define a shared layout for your views, enabling you to encapsulate these common elements.
How can you define a route in ASP.NET Core to be available only for specific HTTP methods using attribute routing?
- [HttpPut], [HttpPost]
- [HttpGet], [HttpPost]
- [HttpDelete], [HttpGet]
- [HttpPatch], [HttpPut]
In ASP.NET Core, you can specify the HTTP methods a route should be available for using attributes like [HttpGet] or [HttpPost] above the controller action method. For example, [HttpGet] ensures the route is available for HTTP GET requests, and [HttpPost] for HTTP POST requests.
You have a page in your application that should be accessible to both authenticated and non-authenticated users. How do you configure this in ASP.NET Core?
- Use [AllowAnonymous] attribute on the controller or action
- Create separate pages for authenticated and non-authenticated users
- Set up two different domains for each user type
- Use cookies to track user access
To make a page accessible to both authenticated and non-authenticated users in ASP.NET Core, you can use the [AllowAnonymous] attribute on the controller or action that corresponds to the page. This attribute allows both types of users to access the page without requiring authentication.
What is the primary purpose of migrations in the context of ASP.NET Core Identity?
- Define database schema for user-related data
- Control user authentication
- Handle user authorization
- Manage user sessions
Migrations in ASP.NET Core Identity are primarily used to define and manage the database schema for user-related data. They allow you to create, update, and evolve the database structure to accommodate changes in your Identity-related models and requirements.
Which method is used to add MVC route handlers and specify the use of default routes?
- AddMvc
- UseRouting
- UseEndpoints
- MapRoute
In ASP.NET Core, the AddMvc method is used to add MVC route handlers and configure the use of default routes. This method sets up MVC services, including routing, and is essential for building web applications with ASP.NET Core MVC. It's typically called within the Startup class's ConfigureServices method.
