What was the primary purpose of the project.json file in earlier versions of ASP.NET Core?
- Managing NuGet Package References
- Configuring Web Server Settings
- Defining Compilation Options
- Storing User Authentication Data
In earlier versions of ASP.NET Core, the project.json file was primarily used for managing NuGet package references. It provided a simple and convenient way to list and manage the dependencies required for a project, making package management more straightforward than using XML-based formats like the .csproj file.
In the context of Entity Framework Core, what is the primary use of the OnModelCreating method?
- Defining the database schema
- Handling user authentication
- Managing API endpoints
- Creating unit tests
The OnModelCreating method in Entity Framework Core is primarily used for defining the database schema. It allows developers to specify how the application's domain classes map to the database tables, including setting up relationships, keys, and other database-specific configurations. This method is essential for database initialization and migrations.
You are developing a mobile app and need a way for the app to communicate and fetch data from the server. What kind of service in ASP.NET Core would be best suited for this?
- Web API
- Blazor Server
- ASP.NET Core MVC
- SignalR
For mobile apps to communicate with a server, Web API is commonly used. It provides a RESTful way to fetch data and is well-suited for client-server communication in mobile apps.
You've been handed an ASP.NET Core application where the database schema frequently changes. Which feature of Entity Framework Core would be most useful to keep the database in sync with the application model?
- Code-First Migrations
- Model-First Approach
- Database-First Approach
- NoSQL Database
Code-First Migrations in Entity Framework Core allows you to automatically create and update the database schema based on changes to your application's model. This feature is ideal for scenarios where the database schema evolves frequently to match the application's needs.
How does Entity Framework Core handle database migrations?
- Code-First Migrations
- Manually Updating the Database Schema
- Automatic Schema Synchronization
- Third-Party Plugins
Entity Framework Core employs automatic schema synchronization to handle database migrations. It automatically generates and runs SQL scripts to update the database schema to match the model changes. Developers don't need to write migration scripts manually, making it a convenient approach.
In the MVC design pattern, the _________ is responsible for updating the view and processing user input.
- Controller
- Model
- View
- Middleware
In the MVC (Model-View-Controller) pattern, the Controller is responsible for updating the view and processing user input. It acts as an intermediary between the Model (data) and the View (user interface). The Controller receives user requests, processes them, and updates the View accordingly.
You're tasked with creating a custom configuration provider for your ASP.NET Core application. What interface should your custom provider implement?
- IConfigurationProvider
- IConfigurationRoot
- IConfiguration
- IServiceProvider
To create a custom configuration provider for an ASP.NET Core application, your provider should implement the IConfigurationProvider interface. This interface defines methods for reading and updating configuration data, allowing you to extend the configuration capabilities of your application.
While learning about ASP.NET Core, you come across the term "Middleware." In simple terms, what does Middleware in ASP.NET Core refer to?
- The database schema of an ASP.NET Core application
- The physical hardware used in server hosting
- The software components that handle requests and responses in the ASP.NET Core pipeline
- The user interface components of a web application
In ASP.NET Core, Middleware refers to the software components that sit between the web server and the application. Middleware components are responsible for handling HTTP requests and responses, allowing you to add various features and behaviors to your application's request processing pipeline.
Which of the following properties is NOT typically required when creating a new user in ASP.NET Core Identity?
- UserName

- PhoneNumber
While UserName, Email, and PhoneNumber are common properties required when creating a new user in ASP.NET Core Identity, PasswordHash is not typically required. The password is provided as plaintext and is hashed internally by Identity for security.
When configuring static file serving in ASP.NET Core, which property can be set to provide a response when a static file is not found?
- FileNotFoundResponse
- FileServerOptions.NotFound
- NotFoundAction
- DefaultResponse
When configuring static file serving in ASP.NET Core, you can set the NotFound property within the FileServerOptions class to customize the response when a static file is not found. This allows you to control the behavior, such as returning a custom error page or redirecting to a specific URL when a requested static file is missing.
