In ASP.NET Core, how can you enforce an authenticated user to have a specific role to access a resource?
- Use the [Authorize] attribute with the "Roles" parameter
- Use the [AllowAnonymous] attribute
- Use the [Authorize] attribute with the "Permissions" parameter
- Use the [Authorize] attribute without any parameters
To enforce that only users with a specific role can access a resource, you should use the [Authorize] attribute with the "Roles" parameter. This restricts access to users who belong to the specified role.
Which directive in _ViewImports.cshtml allows you to set the base class for the Razor views?
- @inherits
- @model
- @using
- @layout
The correct directive to set the base class for Razor views in _ViewImports.cshtml is @inherits. This directive specifies the full name of the class that the view should inherit from. It allows you to establish a custom base class for all views in a folder or the entire application, enabling you to add shared functionality to your views.
Your application requires some complex queries which might not be easily achievable using LINQ. With Entity Framework Core, how can you directly execute SQL queries against the database?
- FromSqlRaw
- ExecuteSqlCommand
- RunSqlQuery
- QuerySQL
In Entity Framework Core, you can directly execute raw SQL queries against the database using the FromSqlRaw method. This allows you to write custom SQL queries when LINQ isn't suitable for your complex query requirements, but it should be used with caution to prevent SQL injection vulnerabilities.
In a new project, you are given the responsibility to handle user registration. Your senior developer mentions that there's a built-in way in ASP.NET Core to manage users. What is this system called?
- Identity
- Middleware
- Entity Framework
- Dependency Injection
The built-in system in ASP.NET Core to manage users is called ASP.NET Core Identity. It's a framework for handling user authentication, authorization, and account management tasks, making it easier to implement user registration and management in your application.
How does the Razor view engine resolve the directives when multiple _ViewImports.cshtml files exist in different directories of the project?
- Directives in the nearest _ViewImports.cshtml override directives in parent directories
- Directives in parent directories override directives in the nearest _ViewImports.cshtml
- Directives in the nearest _ViewImports.cshtml are combined with directives in parent directories
- Directives in _ViewImports.cshtml are ignored in this scenario
The Razor view engine resolves directives by giving precedence to the nearest _ViewImports.cshtml file in the directory hierarchy. Directives in the nearest file will override those in parent directories, allowing for granular control over view behavior.
The __________ folder in an ASP.NET Core project generally contains view templates.
- Views
- Models
- Controllers
- Migrations
The "Views" folder in an ASP.NET Core project typically contains view templates. These templates are used to define the user interface of the application, including the HTML markup and rendering logic for web pages. Views play a crucial role in separating the presentation layer from the application's logic.
If you want to customize the response sent back to the client based on the type of exception thrown, which feature of ASP.NET Core would you leverage?
- Exception Filters
- Middleware Pipelines
- Custom Error Pages
- Middleware Components
To customize the response sent back to the client based on the type of exception thrown, you would leverage ASP.NET Core's Exception Filters. Exception Filters allow you to intercept exceptions, inspect their type or properties, and then modify the HTTP response accordingly. This is a powerful feature for fine-grained control over error handling and response generation.
Entity Framework Core's capability to work with multiple databases and switch between them based on certain criteria is known as _________.
- Database Switching
- Multi-Database Handling
- Database Providers
- Database Sharding
Entity Framework Core's capability to work with multiple databases and switch between them based on certain criteria is known as "Database Providers." Different database providers, such as Microsoft SQL Server, PostgreSQL, MySQL, etc., can be used with EF Core to interact with various database systems seamlessly.
In a scenario where you have both UseStaticFiles() and UseDefaultFiles() in your Startup.cs, which one should be called first to ensure the default document is correctly served?
- UseStaticFiles()
- UseDefaultFiles()
- It doesn't matter, the order is irrelevant
- UseFileServer()
UseDefaultFiles() should be called before UseStaticFiles() to ensure that default documents (e.g., index.html) are correctly served. UseDefaultFiles() configures the middleware to look for and serve the default documents, and UseStaticFiles() serves static files like CSS, JavaScript, and images. The order is important because UseStaticFiles() might intercept the request before UseDefaultFiles() has a chance to locate and serve the default document.
While going through an ASP.NET Core project, you come across HTML-like elements with attributes prefixed by asp-. What are these elements likely related to?
- External JavaScript files
- Server-side form controls and actions
- Cascading Style Sheets (CSS)
- Images and multimedia content
HTML-like elements with attributes prefixed by asp- are likely related to server-side form controls and actions. These are used to integrate server-side functionality, such as form validation and data binding, into Razor views.
