What is the primary role of the .NET SDK in the context of ASP.NET Core development?
- Building and Compiling ASP.NET Core Applications
- Debugging ASP.NET Core Applications
- Handling Web Server Requests
- Managing Database Connections
The .NET SDK (Software Development Kit) plays a crucial role in ASP.NET Core development by providing the tools necessary for building and compiling ASP.NET Core applications. It includes the command-line interface (CLI) tools like 'dotnet' for project management, building, and running applications. Debugging, database management, and web server request handling are tasks typically handled by other components of the development stack.
In a project review, you noticed that the production database connection string is exposed in appsettings.json. How should you securely manage this connection string in an ASP.NET Core application?
- Use User Secrets
- Encrypt the appsettings.json file
- Store it in an environment variable
- Use a configuration file in the project root
In an ASP.NET Core application, it's not secure to expose sensitive information like a production database connection string in appsettings.json. To securely manage it, you should store it in an environment variable. This approach helps protect sensitive data from accidental exposure and is a best practice for configuration management in production environments.

- Data Serialization
- Code Optimization
- UI Design Patterns
ASP.NET Core provides robust built-in features for security. Authentication and Authorization are fundamental to securing web applications by controlling user access and protecting sensitive data. These features help safeguard your application against unauthorized access and attacks.
In your new job, you're asked to develop a registration system for users. Which feature in ASP.NET Core provides out-of-the-box functionalities for user registration and authentication?
- Identity
- Entity Framework Core
- Middleware
- Dependency Injection
ASP.NET Core Identity is a built-in membership system that provides out-of-the-box functionalities for user registration and authentication. It simplifies tasks like user management, password hashing, and role-based authorization in ASP.NET Core applications.
Which of the following views would most likely correspond to the user registration process in an ASP.NET Core application?
- Login.cshtml
- Home.cshtml
- Register.cshtml
- Profile.cshtml
The Register.cshtml view typically corresponds to the user registration process in an ASP.NET Core application. This view usually contains the registration form where users can enter their information to create an account.
How can you restrict certain routes to be accessed only via specific HTTP methods in ASP.NET Core MVC?
- Using Attribute Routing
- By configuring the "app.UseRouting()" middleware
- Through the "ActionFilterAttribute"
- By modifying the "Startup.cs" file
You can restrict routes to specific HTTP methods in ASP.NET Core MVC using attribute routing. By decorating your controller actions or route templates with attributes like [HttpGet] or [HttpPost], you specify which HTTP methods are allowed to access those routes.
