To enforce a consistent structure and look across multiple views, developers use a ________ page in Razor.
- Master
- Index
- Layout
- Partial
To enforce a consistent structure and look across multiple views, developers use a Layout page in Razor. Layout pages define the common structure, such as headers and footers, shared across multiple views, ensuring a cohesive design.
Which protocol does SignalR use primarily before falling back to other techniques?
- WebSocket
- HTTP
- FTP
- TCP
SignalR primarily uses the WebSocket protocol for real-time communication due to its low latency and bidirectional capabilities. WebSocket provides a full-duplex communication channel, making it ideal for applications requiring instant updates. SignalR gracefully falls back to other techniques like HTTP long polling or Server-Sent Events for compatibility with older browsers or network restrictions.
In an ASP.NET Core project, where are the application's dependencies and SDKs defined?
- appsettings.json
- Startup.cs
- project.json
- .csproj files
In an ASP.NET Core project, application dependencies and SDK versions are typically defined in the .csproj files. These files specify the packages, libraries, and tools required for the project. The .csproj files play a crucial role in managing the project's dependencies and ensuring the correct versions are used.
You've just started working on an ASP.NET Core project that uses Identity for user management. What are migrations primarily used for in this context?
- Managing the database schema
- Managing user authentication
- Managing user roles
- Managing user sessions
In an ASP.NET Core project with Identity, migrations are primarily used for managing the database schema. They allow you to create, update, and version your database schema as your application evolves. This is crucial for user management as it involves the creation and maintenance of user-related tables.
SignalR is known for enabling ________ communication, which allows the server to push content to connected clients.
- Real-time
- Batch
- Asynchronous
- Synchronous
SignalR is a library in ASP.NET Core known for enabling real-time communication. It allows the server to push content to connected clients in real-time, making it ideal for applications that require instant updates, such as chat apps and live dashboards.
When combining multiple [Authorize] attributes on a single action or controller, how does ASP.NET Core evaluate the requirements?
- Logical AND
- Logical OR
- Randomly
- Sequentially
ASP.NET Core evaluates the requirements of multiple [Authorize] attributes logically using AND. This means all authorization requirements specified in these attributes must be met for a user to access the action or controller.
You're new to ASP.NET Core and are confused about where to specify the common design elements (like headers and footers) that appear on every page. Which Razor concept should you explore for this purpose?
- ViewComponents
- Razor Layouts
- Partial Views
- Tag Helpers
To specify common design elements like headers and footers that appear on every page, you should explore Razor Layouts. Razor Layouts allow you to define a shared layout for your views, enabling you to encapsulate these common elements.
How can you define a route in ASP.NET Core to be available only for specific HTTP methods using attribute routing?
- [HttpPut], [HttpPost]
- [HttpGet], [HttpPost]
- [HttpDelete], [HttpGet]
- [HttpPatch], [HttpPut]
In ASP.NET Core, you can specify the HTTP methods a route should be available for using attributes like [HttpGet] or [HttpPost] above the controller action method. For example, [HttpGet] ensures the route is available for HTTP GET requests, and [HttpPost] for HTTP POST requests.
You have a page in your application that should be accessible to both authenticated and non-authenticated users. How do you configure this in ASP.NET Core?
- Use [AllowAnonymous] attribute on the controller or action
- Create separate pages for authenticated and non-authenticated users
- Set up two different domains for each user type
- Use cookies to track user access
To make a page accessible to both authenticated and non-authenticated users in ASP.NET Core, you can use the [AllowAnonymous] attribute on the controller or action that corresponds to the page. This attribute allows both types of users to access the page without requiring authentication.
What is the primary purpose of migrations in the context of ASP.NET Core Identity?
- Define database schema for user-related data
- Control user authentication
- Handle user authorization
- Manage user sessions
Migrations in ASP.NET Core Identity are primarily used to define and manage the database schema for user-related data. They allow you to create, update, and evolve the database structure to accommodate changes in your Identity-related models and requirements.
