In a Razor form, how can you prevent the form from being submitted if client-side validation fails?
- Using the onsubmit attribute
- Using the required attribute
- Using the data-val attribute
- Using the no-submit attribute

If you were to create a page in an ASP.NET Core MVC application that displays a list of movies, which component would be responsible for determining how this list is presented to the user?
- View
- Controller
- Model
- Middleware
The View component in ASP.NET Core MVC is responsible for determining how data is presented to the user. It defines the layout and structure of the page, including how the list of movies is displayed. The Controller manages user requests and interacts with the Model to retrieve the necessary data.
You read about exception handling middleware in ASP.NET Core and decide to implement one. However, after adding it, you notice that your custom error handling logic isn't being triggered. What could be a common mistake leading to this issue?
- Incorrect Middleware Order
- Incorrect HTTP Status Codes
- Missing Exception Filters
- Unused Try-Catch Blocks
A common mistake leading to the issue of custom error handling logic not being triggered is incorrect middleware order. Middleware in ASP.NET Core is executed in the order they are added, and exception handling middleware should be placed early in the pipeline to capture exceptions before other middleware processes the request.
You're new to ASP.NET Core and hear about Entity Framework Core. What is the main purpose of using Entity Framework Core in web applications?
- Handling User Authentication
- Creating User Interfaces
- Managing Database Operations
- Hosting Web Services
Entity Framework Core (EF Core) is primarily used for managing database operations in web applications. It provides an object-relational mapping (ORM) framework, allowing developers to work with databases using .NET objects, thus reducing the need to write extensive SQL code.
The ________ method in the "Startup.cs" file is used to add and configure middleware services to the application's request pipeline.
- ConfigureServices
- Configure
- UseMiddleware
- AddMiddleware
In the "Startup.cs" file of an ASP.NET Core application, the "ConfigureServices" method is used to add and configure middleware services. Middleware services are components that handle requests and responses as they flow through the application's request pipeline. The "ConfigureServices" method is where you register services such as database connections, authentication, and dependency injection.
How can you configure Entity Framework Core to use lazy loading for navigation properties?
- Using the .Include() method
- Enabling it in the DbContext configuration
- Setting UseLazyLoadingProxies to true
- Manually fetching related entities
Entity Framework Core (EF Core) uses lazy loading proxies to enable lazy loading for navigation properties. To configure it, you can set the UseLazyLoadingProxies option to true in the DbContext's configuration. This allows EF Core to create dynamic proxies for your entities, enabling lazy loading for related entities.
To override the default routing conventions in MVC, you can use the _________ attribute on your action methods.
- Route
- Controller
- Action
- HTTPGet
To override the default routing conventions in ASP.NET Core MVC, you can use the "Route" attribute on your action methods. This attribute allows you to specify custom routing patterns, such as route templates and parameters, for fine-grained control over URL routing in your application.
You're working on an e-commerce platform and need to create a route for a product details page which takes a product ID as a parameter. Using attribute routing, how would you set up this route?
- [Route("products/details/{id:int}")]
- [HttpGet("products/details/{productID}")]
- [Route("products/details")]
- [Route("products/{id}")]
To set up a route for a product details page with a product ID parameter using attribute routing, you should use [Route("products/details/{id:int}")]. The ':int' constraint specifies that the 'id' parameter must be an integer.
