After writing your ASP.NET Core application code, you want to build and run your application using a command-line tool. Which tool would you use for this purpose?
- dotnet build
- npm start
- ng serve
- python run
To build and run an ASP.NET Core application from the command line, you would use the dotnet build command. This command compiles your application and prepares it for execution.
In Razor forms, the _______ tag helper can be used to generate hidden input fields.
- @Html.Hidden
In Razor forms, you can use the @Html.Hidden tag helper to generate hidden input fields. This is commonly used when you need to include data in the form that should be submitted but not displayed to the user. Hidden fields are often used to store things like unique identifiers or state information.
You are tasked with storing custom logging settings for different environments (e.g., Development, Staging, Production) in an ASP.NET Core project. Which mechanism should you primarily use?
- Environment Variables
- AppSettings.json
- Hardcoding in Code
- Database Storage
In ASP.NET Core, the recommended way to store configuration settings for different environments is by using appsettings.json files. These files can contain environment-specific configuration sections, allowing you to maintain settings separately for Development, Staging, and Production environments without modifying the code.
Imagine you have two action methods in your controller: one for handling the creation of products and another for displaying a specific product's details based on its ID. How can you utilize attribute routing to distinguish these two methods?
- [HttpGet("products/create")] and [HttpGet("products/details/{id}")]
- [Route("create")] and [Route("details/{id}")]
- [HttpGet("{controller=Products}/create")] and [HttpGet("{controller=Products}/details/{id}")]
- [HttpGet("{action=create}")] and [HttpGet("{action=details}/{id}")]
Attribute routing allows you to specify route templates for actions directly within your controller using attributes like [HttpGet] and [Route]. To distinguish the two methods, you can use attribute routing like [HttpGet("{controller=Products}/create")] for product creation and [HttpGet("{controller=Products}/details/{id}")] for displaying product details, providing clear and distinct routes for each action.
In the context of user registration in ASP.NET Core, what does validation primarily ensure?
- Ensures that users provide a valid email address
- Ensures that users enter a strong password
- Ensures that users are above a certain age
- Ensures that users have a specific username
In the context of user registration in ASP.NET Core, validation primarily ensures that users provide a valid email address. This is important for sending account confirmation emails and maintaining accurate user information in the system. It's a critical step in verifying the authenticity of user accounts.
_________ is a practice where code and test are written together, iteratively improving each other.
- Test-Driven Development (TDD)
- Code-First Development
- Model-View-Controller (MVC)
- Behavior-Driven Development (BDD)
Test-Driven Development (TDD) is a software development methodology where tests are written before the actual code. Developers write small, focused tests that guide the development process, helping ensure that the code meets the requirements and is thoroughly tested.
The _________ class in ASP.NET Core Identity is particularly useful for creating and managing users.
- UserManager
- RoleManager
- AuthenticationService
- SecurityManager
The UserManager class in ASP.NET Core Identity is a vital component for creating, updating, and managing user accounts. It provides methods for tasks like creating users, assigning roles, and resetting passwords, making it an essential part of user management in ASP.NET Core applications.
The _________ method of UserManager can be used to check if a user with a specific email address already exists.
- CheckEmailExists
- IsEmailExist
- FindByEmailAsync
- EmailExists
The 'FindByEmailAsync' method of UserManager can be used to check if a user with a specific email address already exists. This method searches for a user with the given email and returns the user if found.
How does the "Controller" in the MVC design pattern typically receive user input in ASP.NET Core?
- Through URL Parameters
- Through the View
- Through HTTP Request
- Through Model Binding
The "Controller" in the MVC design pattern typically receives user input in ASP.NET Core through HTTP requests. It listens to incoming HTTP requests, extracts user input data from the request, and then processes it to determine the appropriate action to take.
When you attempt to create a user programmatically in ASP.NET Core, and the creation fails, what type of object can be checked to obtain the reasons for the failure?
- IdentityResult
- ApplicationUser
- UserManager
- RoleManager
When creating a user programmatically using ASP.NET Core Identity, the CreateAsync method typically returns an IdentityResult object. This object can be checked to obtain detailed information about the reasons for the failure, such as validation errors or other issues encountered during user creation.
