Need to practice your ASP.NET (Core) MVC skills for an upcoming job interview? Try solving these ASP.NET (Core) MVC interview questions that test knowledge of Razor, Action methods and attributes, and other skills. We’ll provide feedback on your answers, and you can use a hint if you get stuck.
These ASP.NET (Core) MVC interview questions are examples of real tasks used by employers to screen candidates for web development jobs that require knowledge of the MVC pattern, ASP.NET and the .NET Framework in order to build robust and scalable web applications.
1. Action Attributes
ASP.NET (Core) MVC
Action attributes
Actions
Public
ASP.NET (Core) MVC
ASP.NET (Core) MVC extends the traditional ASP.NET framework and allows developers to author pages using the model–view–controller (MVC) architecture.
Action attributes
These attributes give ASP.NET developers a way to modify an action's behaviour using declarative syntax.
Actions
Action methods are responsible for executing requests and generate responses to them. They are essential to ASP.NET MVC as they are in charge of defining a response to user interaction.

Which statements are true about action attributes in ASP.NET (Core) MVC?
(Select all acceptable answers.)
If an action returns JSON data, it must be decorated with the JsonResult attribute.
There is a built-in attribute for defining view name.
The ValidateAntiForgeryToken attribute prevents CSRF attacks.
The ActionName attribute allows usage of a different action name than the method name.
2. Passing Data
ASP.NET (Core) MVC
MVC pattern
Public
ASP.NET (Core) MVC
ASP.NET (Core) MVC extends the traditional ASP.NET framework and allows developers to author pages using the model–view–controller (MVC) architecture.
MVC pattern
The MVC pattern is designed to split an application into three logical parts: the model, the view and the controller. The model is responsible for the data and the rules of the application. The view is responsible for outputting that information, and the controller is responsible for accepting input from a user and forwarding it to the model or the view. Every web developer should be familiar with the MVC pattern and the benefits of encapsulating these components.

Select all the methods that can be used to pass data from the controller to the view.
(Select all acceptable answers.)
By setting properties on the model that is passed to the view.
By setting properties on the web controls that the view contains.
By using the view's helper methods.
By using ViewData dictionary.
3. Meal View

Public
ASP.NET (Core) MVC
ASP.NET (Core) MVC extends the traditional ASP.NET framework and allows developers to author pages using the model–view–controller (MVC) architecture.
Razor
Razor is an ASP.NET programming syntax used to create dynamic web pages with the C# or Visual Basic .NET programming languages. It is the most popular of the view engine syntaxes available in ASP.NET MVC.
View
A view is the component responsible for presenting an applications data to its users. A view's representations can take many forms, such as HTML templates, charts and diagrams. Every web developer should understand the concept of encapsulating the render logic within a view and the benefits to development that provides.

Consider the following C# model:
public class Meal
{
public string Name { get; set; }
public double Calories { get; set; }
public List<string> Ingredients { get; set; }
}
The following template for Razor view engine accepts a Meal as model. Fill in the blanks with the simplest variants so that correct properties are printed.
<html>
<body>
<h1>Name: </h1>
<p>Calories: </p>
<p>Ingredients:</p>
<ul>
@foreach (var ingredient in )
{
<li></li>
}
</ul>
</body>
</html>

Add appropriate routing attributes to the GetUsers and GetUserById actions so that:
- GetUsers should activate on URL "/users".
- GetUserById should activate on URLs "/users/userId" where userId is a string that represents the id of the user.
ASP.NET Core MVC Web 2 app, C# 8.0, .NET Framework 4.8
- The GetUser action is correctly routed: Wrong answer
- The GetUserById action is correctly mapped: Wrong answer

Consider the following view, provided here and below, which is placed in Views/Address/Create.cshtml:
@model Address
<!DOCTYPE html>
<html>
<head>
<title>Create a new address</title>
</head>
<body>
<form method="post" action="/user/address/save">
<label asp-for="Street">Street:</label>
<input type="text" asp-for="Street" />
<label asp-for="City">City:</label>
<input type="text" asp-for="City" />
<input type="submit" value="Submit" />
</form>
</body>
</html>
Add actions to the AddressController so that:
- On requests to "user/address/create", the view above should be returned.
- On submitting the form from the view above, AddressController should add the Address that was submitted into the AddressController.addresses field and then redirect to the "user/address/create" URL.
Actions should use attribute routing.
ASP.NET Core MVC Web 2 app, C# 8.0, .NET Framework 4.8
- /user/address/create and /user/address/save URLs are mapped to distinct actions: Wrong answer
- /user/address/create URL returns expected view: Wrong answer
- Address is added to the AddressController.addresses list when the form is submitted: Wrong answer
- After saving the address, user is redirected to /user/address/create URL: Wrong answer
