You are tasked with setting up an ASP.NET Core environment on a Linux machine. What steps would be essential to ensure the application can be developed, built, and run seamlessly?
- Install .NET Runtime
- Configure IIS
- Set Up Visual Studio
- Configure NGINX
On a Linux machine, the essential step is to install the .NET Runtime to enable ASP.NET Core development. Unlike Windows, IIS is not typically used on Linux, and Visual Studio is primarily a Windows IDE. NGINX is a web server and reverse proxy but isn't required for setting up a development environment.
For creating custom middleware, the delegate needs to accept a _________ and return a Task.
- HttpContext
- HttpRequest
- HttpResponse
- CancellationToken
For creating custom middleware in ASP.NET Core, the delegate used in the middleware pipeline should accept an HttpRequest and return a Task. Middleware operates on the incoming request, and by convention, it often manipulates the request and response. Therefore, it takes an HttpRequest as input. The Task return type allows asynchronous operations to be performed in the middleware.
When might you need to apply Identity migrations in ASP.NET Core?
- When you add or modify user-related data models
- Only during the initial setup
- When you want to improve authentication speed
- When deploying the application
Identity migrations should be applied when you add or modify user-related data models. It's not limited to the initial setup; you should apply migrations whenever there are changes in the Identity-related data structures, such as adding new user properties or changing validation rules.
As a new developer on a team, you're asked to ensure that a custom-built Tag Helper is available across all the Razor views in the project. What steps would you take to achieve this?
- Add the Tag Helper directly to each Razor view where it's needed.
- Register the Tag Helper in _ViewImports.cshtml or the Razor view using @addTagHelper directive.
- Modify the Tag Helper's code to make it available globally.
- Ask other developers to include the Tag Helper in their Razor views.
To make a custom-built Tag Helper available across all Razor views in the project, you should register it in either the _ViewImports.cshtml file or directly in a Razor view using the @addTagHelper directive. This ensures that the Tag Helper is globally accessible and can be used without the need for individual developers to include it in their views.
Which method in the Startup class is commonly used to configure middleware?
- Configure
- ConfigureServices
- UseMiddleware
- ConfigureMiddleware
The Configure method in the Startup class is commonly used to configure middleware in ASP.NET Core. Inside this method, you can specify the order in which middleware components are added to the pipeline and define how they process requests and responses.
The process of mapping an incoming request to a route template is known as _______.
- Routing
- Mapping
- Dispatching
- URL Resolution
The correct term is "Dispatching." Dispatching refers to the process of mapping an incoming HTTP request to a specific route template in your ASP.NET Core application. It's a crucial step in determining which controller and action should handle the request.
You're tasked with building a new feature in an ASP.NET Core application where each user profile should be accessible via a URL like /users/{username}. How can attribute routing facilitate this?
- Use [Route("users/{username}")] on the action method
- Modify the appsettings.json file
- Create a new middleware component
- Add a user-profile route in Startup.cs
In ASP.NET Core, attribute routing allows you to define custom routes for your controllers and action methods. By using the [Route] attribute with the desired route template, you can specify that the user profile should be accessible via /users/{username}.
What is ASP.NET Core primarily used for?
- Data Analysis
- Game Development
- Photo Editing
- Web Application Development
ASP.NET Core is a cross-platform, high-performance framework for building modern, cloud-based, internet-connected applications. Its primary purpose is for web application development, including web APIs, web front-ends, and real-time web apps.
In ASP.NET Core development, which tool would allow you to code and debug on platforms like Linux and macOS, apart from Windows?
- Visual Studio
- Visual Studio Code
- Sublime Text
- Notepad++
Visual Studio Code is the tool that allows you to code and debug ASP.NET Core applications on multiple platforms, including Linux and macOS. It's a lightweight, cross-platform code editor that's highly extensible and well-suited for modern web development.
Which type of testing focuses on testing multiple components of an application together?
- Unit Testing
- Component Testing
- Integration Testing
- Regression Testing
Integration testing concentrates on testing multiple components of an application together. It ensures that these components work correctly when combined and can communicate effectively. It's an essential step between unit testing and system testing in the testing life cycle.
