The @ViewData object is a type of _________, allowing you to pass data from the controller to the view.
- Dictionary
- List
- Class
- Interface
The @ViewData object is a type of Dictionary in ASP.NET Core. It is used to pass data from the controller to the view. ViewData allows you to share data between different parts of your application, making it available for rendering in the view.
What is the primary difference between the Process and ProcessAsync methods when defining a custom Tag Helper?
- Process is synchronous, while ProcessAsync is asynchronous
- Process is for server-side processing, while ProcessAsync is for client-side processing
- Process can only be used in ASP.NET Core, while ProcessAsync is for ASP.NET Framework
- Process is used for tag rendering, while ProcessAsync is for tag parsing
The primary difference between the Process and ProcessAsync methods in custom Tag Helpers is that Process is synchronous, while ProcessAsync is asynchronous. Process is used for synchronous processing and tag rendering, whereas ProcessAsync is employed for asynchronous operations, such as waiting for external data or I/O operations, which is important for responsiveness in modern web applications.
You're building a web application that requires different user roles like "Admin," "User," and "Guest." Using ASP.NET Core Identity, how would you restrict access to certain pages only for the "Admin" role?
- Use [Authorize(Roles = "Admin")] attribute on the controller or action method
- Use [Authorize(Policy = "AdminPolicy")] attribute with a custom policy
- Use [Authorize("Admin")] attribute
- Use [AllowAnonymous] attribute for "Guest"
To restrict access to specific pages for the "Admin" role, you should use the [Authorize(Roles = "Admin")] attribute. This attribute allows only users with the "Admin" role to access the decorated controller or action method.
ASP.NET Core Identity is an extensible system for _________.
- User authentication and authorization
- Game development
- Data analysis
- Photo editing
ASP.NET Core Identity is a framework for user authentication and authorization. It provides robust features for managing user identities, including user registration, login, and role-based access control, making it an essential component for securing ASP.NET Core applications.
In the hierarchy of configuration sources, which source has the highest precedence in determining the final value of a configuration setting in ASP.NET Core?
- Environment Variables
- Command-Line Arguments
- JSON Configuration File
- User Secrets
In ASP.NET Core, configuration sources are considered in a specific order, with command-line arguments having the highest precedence. This means that if a configuration setting is provided via a command-line argument, it will override settings from other sources.
You are tasked with deploying an ASP.NET Core application. Which tool or service would help automate the process of getting new code from a developer's machine to a production environment?
- Jenkins
- Docker
- Azure DevOps
- Visual Studio Code
Azure DevOps is a comprehensive tool for automating the deployment pipeline. It facilitates the automation of code deployment from a developer's machine to a production environment, making it a valuable choice for ASP.NET Core application deployment.
In your new job, you're asked to ensure that user passwords are at least 8 characters long. Where in the ASP.NET Core Identity would you set this requirement?
- IdentityOptions
- Startup.cs
- AccountController.cs
- UserManager
In ASP.NET Core Identity, you can set password requirements like length using the IdentityOptions configuration in the Startup.cs file. This allows you to enforce policies such as minimum password length, special characters, and more.
What advantage does the "Web Application (Model-View-Controller)" template offer over the "Web Application" template in terms of structuring the application?
- It uses Angular for the front-end.
- It provides a clear separation of concerns with the MVC pattern.
- It has built-in authentication and authorization.
- It supports only RESTful APIs.
The "Web Application (Model-View-Controller)" template follows the MVC pattern, which enforces a clear separation of concerns between the model (data), view (presentation), and controller (logic). This separation makes it easier to manage and maintain the application as it grows in complexity. The "Web Application" template, on the other hand, may not enforce this separation as strictly.
If you want to code for ASP.NET Core and prefer a lightweight, cross-platform editor, which tool would you likely use?
- Visual Studio
- JetBrains Rider
- Sublime Text
- Visual Studio Code
If you prefer a lightweight, cross-platform editor for coding ASP.NET Core applications, Visual Studio Code is an excellent choice. It offers a wide range of extensions and supports various programming languages, making it a popular choice among developers for web development, including ASP.NET Core.
What is the significance of the @model directive in a Razor view?
- Specifies the layout of the view
- Defines the model class for the view
- Imports external libraries
- Declares a variable
The @model directive in a Razor view specifies the model class that the view expects to receive. It allows you to strongly type the view, enabling compile-time checking and intellisense for model properties in the view. This helps prevent runtime errors and improves code maintainability.
