What is the primary function of the dotnet command when used without any additional arguments in the CLI?
- It compiles the current project and produces an executable binary.
- It installs the latest version of the .NET SDK.
- It displays the help menu for the dotnet CLI.
- It updates all NuGet packages in the current project.
When the dotnet command is used without any additional arguments, it displays the help menu for the .NET CLI. This menu provides a list of available commands and options, helping developers navigate and use the CLI effectively. It's a handy way to explore the CLI's capabilities and understand how to use various commands and options.
You've been tasked to deploy an ASP.NET Core application to a cloud platform that supports scaling out based on demand, but you want to minimize management overhead. Which service would be the best fit?
- Azure Kubernetes Service (AKS)
- Azure Functions
- Azure App Service
- Azure Virtual Machines (VMs)
In this scenario, Azure App Service would be the best fit. Azure App Service is a platform-as-a-service (PaaS) offering that abstracts much of the infrastructure management. It allows you to easily deploy and scale web applications without the overhead of managing virtual machines or container orchestrators like AKS.
In a team development scenario, two developers have created separate migrations for different features at the same time. Before merging these changes into the main branch, what precautions or steps should be taken regarding the Identity migrations?
- Delete one developer's migrations to avoid conflicts
- Ensure both developers use the same database provider
- Collaborate to combine the migrations and resolve conflicts
- Let Entity Framework Core handle the merge automatically
When multiple developers work on separate migrations, it's essential to collaborate and combine the migrations before merging into the main branch. This prevents conflicts and ensures a consistent database schema. Entity Framework Core doesn't handle automatic merge of migrations, so developers need to coordinate their efforts to avoid issues.
In an e-commerce application, after a user successfully checks out, you want to redirect them to a confirmation page. Which action result can achieve this redirection?
- Redirect
- Ok
- View
- BadRequest
To achieve a redirection after a successful action, you should use the Redirect action result. It allows you to specify the URL to which the user should be redirected, typically a confirmation page in this case. The Redirect result returns an HTTP 302 status code, indicating a temporary redirect.
If you want to enforce that passwords must contain a non-alphanumeric character in ASP.NET Core Identity, which property should you set?
- RequireNonAlphanumeric
- RequireUppercase
- RequireDigit
- RequireLowercase
In ASP.NET Core Identity, the RequireNonAlphanumeric property should be set to true if you want to enforce that passwords must contain at least one non-alphanumeric character (e.g., special symbol). This adds an extra layer of security to user passwords.
The session information in ASP.NET Core is stored using _________ by default.
- Cookies
- Local Storage
- Session Storage
- Database
In ASP.NET Core, session information is typically stored using cookies by default. Cookies are small pieces of data sent from a web server and stored on the client's browser. They are commonly used to maintain user state and session data across HTTP requests, making them suitable for storing session information.
Dependency injection in ASP.NET Core MVC allows services to be injected into controllers via their _________.
- Constructors
- Properties
- Methods
- Fields
Dependency injection in ASP.NET Core MVC allows services to be injected into controllers via their constructors. This approach promotes the use of constructor injection for better testability and maintainability of your controllers, ensuring that required services are provided when the controller is created.
In scenarios with table splitting in Entity Framework Core, how is it ensured that multiple entities map to a single table?
- Using the .ToTable() method with the same table name
- Manually specifying the same columns for multiple entities
- Table splitting doesn't allow multiple entities in one table
- By using the .MapToStoredProcedures() method
To ensure that multiple entities map to a single table in table splitting scenarios, you can use the .ToTable() method with the same table name for both entities. This tells Entity Framework Core to store both entities in the same table in the database.
What is the primary purpose of Razor views in ASP.NET Core?
- Defining database models
- Handling HTTP requests
- Creating user interfaces
- Managing server configurations
Razor views in ASP.NET Core are primarily used for creating user interfaces. They allow developers to define the structure and layout of web pages by mixing HTML markup with C# or VB.NET code. Razor views enable dynamic content rendering and help build the presentation layer of web applications.
What is a primary advantage of using ASP.NET Core Identity over custom authentication systems?
- Built-in Security Features
- Lower Development Cost
- Greater Flexibility
- Faster Performance
One of the primary advantages of using ASP.NET Core Identity is its built-in security features. It handles common security concerns like password hashing, account lockout, and two-factor authentication, saving developers from implementing these features manually. This enhances application security.
