How do you enable or disable a specific tag helper in a Razor view?
- By adding/removing it from _ViewImports.cshtml
- By using the [TagHelper] attribute
- By configuring it in the appsettings.json file
- By setting a boolean flag in the Razor view
You can enable or disable a specific Tag Helper in a Razor view by adding or removing it from the _ViewImports.cshtml file. This file is where you list the Tag Helpers that should be available to all views in the directory. By including or excluding a Tag Helper here, you control whether it's active for a particular view or set of views.
In the context of project.json, what is signified by the "dependencies" section?
- External Libraries and Packages Used by the Project
- Database Connection Strings
- Application Startup Configuration
- User Authentication Settings
In the context of project.json, the "dependencies" section signifies the external libraries and packages that the project relies on. These dependencies are automatically downloaded and managed by NuGet, ensuring that the required packages are available for the project to function correctly.
Besides the wwwroot folder, you can also specify custom _________ to determine from where the static files should be served.
- Middleware
- Routes
- File Providers
- Controllers
In ASP.NET Core, you can specify custom file providers to determine from where the static files should be served. This allows flexibility in serving static content from different locations, not just the "wwwroot" folder.
You've been asked to build a feature where the application should display products based on categories like /products/electronics or /products/books. How can you design your routes using attributes to achieve this?
- Use [Route("products/{category}")] on the action method
- Modify the Global.asax file
- Configure routes in web.config
- Use [RoutePrefix("products/{category}")] on the controller
To achieve this, you can use attribute routing with a parameter placeholder like {category} in the route template. By applying [Route("products/{category}")] to the action method, you can ensure that products are displayed based on the specified category in the URL.
If you want a route to match only when a specific query string is present, which type of route constraint can you use?
- Regex
- Range
- Required
- Bool
To match a route only when a specific query string is present, you can use the "Required" route constraint. This constraint ensures that the specified query parameter is included in the request, making the route match only when the query string contains that parameter.
Which Entity Framework Core feature allows developers to apply changes in the application model to the database schema?
- Migrations
- Seeding
- Scaffolding
- Query Optimization
Entity Framework Core migrations allow developers to apply changes in the application model to the database schema. Migrations are scripts that capture changes to the database schema over time, making it easy to update the database as the application evolves without losing data.
While navigating an ASP.NET Core project, you come across various folders named "Controllers," "Models," and "Views." This organizational structure is indicative of which design pattern?
- Model-View-Controller (MVC)
- Singleton Pattern
- Observer Pattern
- Factory Method Pattern
The organizational structure of "Controllers," "Models," and "Views" in an ASP.NET Core project is indicative of the Model-View-Controller (MVC) design pattern. MVC separates an application into three interconnected components, making it easier to manage and maintain code. Controllers handle user requests, Models manage data and business logic, and Views handle user interfaces.
You've been asked to configure the system so that users who forget their passwords can reset them using a link sent to their email. Which feature in ASP.NET Core Identity supports this functionality?
- UserManager
- EmailSender
- ResetPasswordToken
- TwoFactorAuthentication
To allow users to reset their passwords using an email link, you would need to utilize the EmailSender feature in ASP.NET Core Identity. This involves sending a password reset email with a secure token that users can use to reset their passwords securely.
If a developer wants to include client-side libraries in their project, they would modify the ________ file in an ASP.NET Core project.
- appsettings.json
- Startup.cs
- .csproj
- wwwroot/libraries.txt
To include client-side libraries in an ASP.NET Core project, a developer would typically modify the ".csproj" (C# project) file. This file contains references to NuGet packages, project dependencies, and other configuration settings, including client-side libraries like JavaScript or CSS files. Modifying the ".csproj" file allows you to manage these dependencies effectively.
Before the introduction of .csproj in .NET Core 2.0 and later, which file was used to define the project configuration?
- project.json
- .csproj
- settings.config
- config.json
Before the introduction of .csproj in .NET Core 2.0 and later, the project configuration was defined using the project.json file. This file contained information about dependencies, target frameworks, and other project-specific settings. However, with the transition to .csproj files, project.json was replaced, and project configuration became part of the .csproj file and associated .csproj.user files.
