After completing the development of a feature, you decide to run tests to ensure that your new code doesn't break existing functionality. What is this type of testing called?
- Regression Testing
- Performance Testing
- Usability Testing
- Smoke Testing
Running tests after developing a new feature to ensure that existing functionality remains unaffected is known as Regression Testing. It helps catch unintended side effects or bugs introduced by new code changes.
You've been asked to modify the configurations that get loaded during the startup of your ASP.NET Core application. Which file should you primarily focus on?
- Startup.cs
- appsettings.json
- Program.cs
- HomeController.cs
In an ASP.NET Core application, the Startup.cs file is where you primarily configure the application's services, middleware pipeline, and other startup-related settings. This is where you can modify how the application behaves during startup.
In a certain scenario, you want to display a list of items in multiple views without repeating the same HTML and C# code. What would be the best approach in Razor views?
- Razor Sections
- Razor Partials
- Razor Components
- Razor Views
Razor Partials are reusable components in Razor views. They allow you to define a piece of HTML and C# code once and then include it in multiple views. This approach ensures code reusability and reduces duplication.
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.
Which method is used to add MVC route handlers and specify the use of default routes?
- AddMvc
- UseRouting
- UseEndpoints
- MapRoute
In ASP.NET Core, the AddMvc method is used to add MVC route handlers and configure the use of default routes. This method sets up MVC services, including routing, and is essential for building web applications with ASP.NET Core MVC. It's typically called within the Startup class's ConfigureServices method.
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.
