When dealing with the "Database First" approach in EF Core, which command is often used to scaffold the database structure?
- Scaffold-Database
- Update-Database
- Add-Migration
- Scaffold-Model
In the "Database First" approach, developers typically use the "Scaffold-Database" command to reverse engineer the database structure and generate corresponding entity classes in Entity Framework Core. This command helps in creating the model based on an existing database.
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.
Which of the following is a unique feature introduced in ASP.NET Core that wasn't present in the traditional ASP.NET?
- Cross-platform Support
- Web Forms
- Windows-only Development
- COM Interoperability
One of the standout features of ASP.NET Core is its cross-platform support. Unlike traditional ASP.NET, which was primarily designed for Windows-based development, ASP.NET Core is cross-platform and can run on Windows, macOS, and Linux. This flexibility is a key differentiator and allows developers to target a broader range of platforms.
What would be the primary reason to implement a "terminal" middleware in your application?
- Handling request and response caching
- Handling authentication and authorization
- Performing logging and diagnostics
- Modifying the HTTP response before it's sent
A "terminal" middleware is typically used to modify the HTTP response just before it's sent to the client. This is often used for tasks like adding custom headers, compressing content, or performing other response-related tasks. Terminal middleware allows you to make final adjustments to the response before it leaves the application, making it a key component for response customization.
While working on an ASP.NET Core application, you realize you need functionalities like Git integration, debugging, and extensions. Which lightweight editor, enriched with plugins, would be ideal for this purpose?
- Visual Studio
- Sublime Text
- Visual Studio Code
- Notepad++
Visual Studio Code (VS Code) is a lightweight, extensible code editor that's well-suited for ASP.NET Core development. It supports Git integration, debugging, and offers a wide range of extensions, making it an ideal choice for developers looking for a versatile and customizable development environment.
In ASP.NET Core Identity, what is primarily used to add additional properties to the user model?
- ApplicationUser Class
- ApplicationDbContext
- IdentityRoles
- Microsoft.EntityFrameworkCore
In ASP.NET Core Identity, developers typically create a custom class, often named "ApplicationUser," which inherits from the built-in IdentityUser class. This custom class is used to add additional properties to the user model, such as user-specific data that your application requires beyond the default user attributes.
You're learning about ASP.NET Core MVC and come across an example where the controller returns a webpage. Which action result is this likely using?
- ViewResult
- JsonResult
- RedirectToActionResult
- ContentResult
When a controller returns a webpage in ASP.NET Core MVC, it typically uses a ViewResult. A ViewResult represents an HTML page that is rendered to the client. It's commonly used to generate HTML views for web applications.
In ASP.NET Core Identity, to create a user with specific claims, one can use the 'AddClaimsAsync' method after the user has been created using _________ method.
- 'CreateAsync'
- 'AddUserAsync'
- 'RegisterAsync'
- 'InitializeAsync'
In ASP.NET Core Identity, you create a user with the 'CreateAsync' method. Afterward, you can use the 'AddClaimsAsync' method to associate claims with the user. Claims are often used to store user-specific information or permissions.
What does the DbSet property in a DbContext represent?
- A collection of entity objects for a specific entity type
- A connection string to the database
- A stored procedure
- A view in the database
The DbSet property in a DbContext represents a collection of entity objects for a specific entity type. It acts as a DbSet that allows you to query, insert, update, and delete records of that entity type in the corresponding database table. It provides a convenient way to work with entities as if they were in-memory objects while abstracting the underlying database operations.
