- _ViewImports.cshtml
- _Layout.cshtml
- _ViewStart.cshtml
- web.config
The _ViewImports.cshtml file is responsible for defining common using directives and shared code that are automatically available to all Razor views in an ASP.NET Core project. It centralizes the configuration for views, promoting code reuse and consistency.
Which component of the ASP.NET Core development environment allows for dependency resolution and package management?
- .NET Compiler
- NuGet Package Manager
- ASP.NET Core Runtime
- Entity Framework Core
The NuGet Package Manager is the component of the ASP.NET Core development environment that handles dependency resolution and package management. It is a powerful package manager that helps developers manage and integrate third-party libraries and packages seamlessly into ASP.NET Core projects.
Your college project involves creating a simple blog. Which ASP.NET Core template provides functionalities like user comments and posts out of the box?
- Web API
- Empty
- MVC
- Blazor
The ASP.NET Core MVC template is ideal for creating a simple blog. It provides built-in features for handling user comments and posts. MVC (Model-View-Controller) is a pattern that separates the application into components for managing data, the user interface, and the control flow, making it suitable for this scenario.
In a tutorial, you see a Razor form with the attribute asp-controller="Home". What does this attribute indicate?
- The name of the submit button
- The HTML form method
- The name of the controller handling the form
- The CSS class of the form
The asp-controller attribute in a Razor form indicates the name of the controller that will handle the form submission. This attribute is part of the Razor Pages and MVC conventions in ASP.NET Core, helping to route the form data to the appropriate controller action.
A new developer joins your team and is unfamiliar with the structure of ASP.NET Core projects. They ask you where the core application logic, such as controllers and models, resides. What would be your response?
- Controllers are in the "Views" folder, and models are in the "Controllers" folder.
- Controllers are in the "Models" folder, and models are in the "Views" folder.
- Controllers are in the "Controllers" folder, and models are in the "Models" folder.
- Controllers and models are both in the root directory.
In ASP.NET Core, the core application logic is typically organized as follows: Controllers are in the "Controllers" folder, and models are in the "Models" folder. This structure helps maintain a clean separation of concerns and follows the convention over configuration (CoC) principle.
What is the primary advantage of using ASP.NET Core Identity for user management in your web application?
- Simplified User Authentication
- Faster Page Load Times
- Enhanced UI Design
- Improved SEO Ranking
ASP.NET Core Identity offers a comprehensive solution for user authentication and management. Its primary advantage lies in providing simplified user authentication, allowing developers to focus on building features rather than reinventing user management functionalities. It includes features like user registration, login, password reset, and role-based authorization out of the box.
In a blogging platform built with ASP.NET Core MVC, when a user submits a new blog post, which component would handle the validation and submission process?
- Controller
- View
- Model
- Middleware
The Controller component in the MVC pattern is responsible for handling user input, including validation and processing. In this scenario, it would handle the validation and submission process when a user submits a new blog post. The Controller receives the user's input, validates it, interacts with the Model to save the data, and then updates the View if necessary.
When designing a Razor Layout in ASP.NET Core, which directive is used to render the main body content of child views?
- @RenderBody()
- @RenderContent()
- @IncludeBody()
- @RenderSection("MainContent")
In an ASP.NET Core Razor Layout, you use @RenderBody() directive to render the main body content of child views. This directive tells the layout to include the content from the child view. The other options are either incorrect or not commonly used for this purpose.
When working with Identity migrations, what happens if there's a conflict between two migrations?
- A migration error occurs, and you must resolve it manually.
- The migrations are applied sequentially without any issues.
- The conflicting migrations are merged automatically.
- ASP.NET Core doesn't support conflicting migrations in Identity.
In case of a conflict between two Identity migrations, a migration error occurs, and it must be resolved manually by the developer. Conflicts can arise when two migrations attempt to modify the same Identity-related tables or data.
What is the main difference between [Authorize] and [AllowAnonymous] attributes?
- [Authorize] allows access only to authenticated users, while [AllowAnonymous] allows access to all users.
- [Authorize] allows access to all users, while [AllowAnonymous] allows access only to authenticated users.
- [Authorize] is used for authentication, while [AllowAnonymous] is used for authorization.
- [AllowAnonymous] is used for authentication, while [Authorize] is used for authorization.
The main difference is that [Authorize] restricts access to authenticated users by default, whereas [AllowAnonymous] allows access to all users regardless of their authentication status. [Authorize] is primarily for authentication, and [AllowAnonymous] is for allowing access without authentication.
A _________ in a DbContext represents a collection of entities that can be queried from the database.
- DbSet
- EntitySet
- EntityCollection
- EntityList
In Entity Framework Core, a DbSet in a DbContext represents a collection of entities that can be queried from the database. Each DbSet corresponds to a table in the database, and you can use LINQ queries to retrieve data from and manipulate data in these collections. The DbSet is a fundamental concept in Entity Framework Core and serves as the entry point for interacting with database entities.
When defining an attribute route, which of the following attributes would you use to specify a route for an action method?
- [Route]
- [Action]
- [Controller]
- [HttpGet]
To specify a route for an action method using attribute routing in ASP.NET Core, you would use the [Route] attribute. This attribute allows you to define the URL pattern that maps to the action method, giving you fine-grained control over routing behavior.
