You are just starting with ASP.NET Core and are looking at a piece of code in the Startup.cs file with endpoints.MapControllerRoute. What is the purpose of this code?
- Configuring routing for controllers
- Defining a database connection
- Setting up authentication
- Handling exceptions
The code endpoints.MapControllerRoute is used to configure routing for controllers in ASP.NET Core. It defines how incoming HTTP requests should be mapped to controller actions, allowing for dynamic handling of URLs by your application.
Which action result type would be best to use if you want to navigate the user to a different URL from the controller?
- ViewResult
- JsonResult
- PartialViewResult
- RedirectToActionResult
If you want to navigate the user to a different URL from the controller, the best action result type to use is RedirectToActionResult. It issues an HTTP redirect to another action within the same or a different controller, allowing you to redirect the user to a different page or route.
What is the primary function of the dotnet command when used without any additional arguments in the CLI?
- Display a list of available .NET Core versions
- Create a new ASP.NET Core project
- Run the last executed .NET application
- Show information about .NET Core CLI commands
When you use the dotnet command without any additional arguments, it displays information about available .NET Core CLI commands. This helps users understand what commands are available and how to use them effectively.
A colleague has created a Razor form, but you notice that the form data is appended to the URL upon submission, potentially exposing sensitive data. What might be the cause and how would you remedy it?
- The form is using a GET request method
- The form is missing an anti-forgery token
- The form is missing client-side validation
- The form is using AJAX for submission
The cause of the issue is likely that the form is missing an anti-forgery token (CSRF token). Without this token, ASP.NET Core won't accept the POST request, and the form data is sent as part of the URL, which is not secure. To remedy this, you should include the @Html.AntiForgeryToken() in your form and add [ValidateAntiForgeryToken] attribute to the corresponding action method in the controller.
Unit tests ensure that individual _________ of the software work as intended.
- Units
- Modules
- Components
- Pieces
Unit tests are designed to verify that individual units or components of a software application, such as methods or functions, work as intended. These units are typically small, self-contained parts of the software.
Shadow properties are fields that aren't present in your entity class but are represented in the database. You define these using the _________ method in Fluent API.
- HasField
- HasShadow
- AddShadow
- DefineField
Shadow properties are fields that exist only in the database and not in your entity class. You can define these using the HasShadow method in Fluent API when configuring your entity in ASP.NET Core Entity Framework.
When you want to share common Razor directives across multiple views, you would typically use the _______ file.
- _ViewImports.cshtml
- _Layout.cshtml
- _ViewStart.cshtml
- _Shared.cshtml
The correct file to share common Razor directives across multiple views is the "_ViewImports.cshtml" file. It allows you to define namespaces, tag helpers, and other common configurations that should apply to multiple views.
Your team is developing an audit system where every database update or insert should include a timestamp. However, you don't want to include this property in your entity classes. How would you implement this in Entity Framework Core?
- Use Shadow Properties
- Create a Separate Audit Table
- Use Triggers
- Add Timestamp Property to Entity Classes
To achieve this without including the timestamp property in your entity classes, you can use Shadow Properties in Entity Framework Core. Shadow properties are properties that are not defined in your entity classes but are tracked by EF Core for specific purposes like auditing.
In a Dockerized ASP.NET Core application deployment, which command is used to build a Docker image from a Dockerfile?
- docker push
- docker create
- docker build
- docker deploy
To build a Docker image from a Dockerfile, you use the docker build command. The Dockerfile contains instructions for assembling the image, and this command creates the image based on those instructions, making it ready for containerization and deployment.
Imagine you are tasked with creating an e-commerce website where page load speed is a priority, but you also want the benefits of ASP.NET Core. Which project template would be optimal?
- MVC
- Razor Pages
- Web API
- Blazor Server
For an e-commerce website where page load speed is crucial and you want the benefits of ASP.NET Core, the optimal choice would be the Web API project template. Web APIs are designed for delivering data efficiently to clients, making them ideal for scenarios where performance is a priority. You can still leverage the benefits of ASP.NET Core for high-performance web services.
