However, it comes with a trade-off in terms of performance, as additional overhead is required to resolve method calls at runtime. On the other hand, reference types store a reference to the memory location where the actual data resides, typically on the heap. When a reference type variable is assigned to another, both variables point to the same memory location.

  • It indicates whether more than one instance of the error filter attribute can be specified.
  • Routing in ASP.NET MVC is responsible for mapping incoming HTTP requests to appropriate controller actions, enabling clean and user-friendly URLs.
  • Razor provides a new view engine with a streamlined code for focused templating.
  • Some common ASP.NET MVC interview questions for experienced developers include topics like routing, model binding, data access, dependency injection, unit testing, and security.

Catching these broad exceptions can make it difficult to identify and debug issues since they encompass a wide range of error types. Instead, focus on handling specific exceptions relevant to your code’s functionality. The default route prevents requests for a web resource file such as Webresource.axd or ScriptResource.axd from being passed to the controller. To add routes to a webform application, we use MapPageRoute() method of the RouteCollection class, while for adding routes to an MVC application, we use MapRoute() method. MVC is a software architecture pattern for developing web applications. ViewBag is a dynamic property that is used to pass data from a Controller action to a View.

How can we pass model data to the view ?

As a result, changes made to one variable will also be reflected in the other. Examples of reference types include object, string, arrays, and user-defined classes. Synchronous action methods in ASP.NET Core MVC execute sequentially, blocking subsequent requests until completion. Asynchronous action methods, on the other hand, allow concurrent processing of multiple requests using async/await keywords, improving scalability and responsiveness. The primary purpose of appsettings.json is to store key-value pairs that can be accessed throughout the application using dependency injection or IConfiguration interface. This allows developers to separate environment-specific configurations (e.g., database connection strings, API keys) from code, making it easier to maintain and deploy across different environments.

You can work as an MVC developer even with a bachelor’s degree and upgrade your skills. However, for better career prospects, having a master’s degree may be useful. You should be familiar with the popular client-side frameworks such as jQuery, Angular, and React. You must check out the official job description to check if the company has specified some framework or version in particular. It has several derived classes like JsonResult, ViewResult, and FileStreamResult. Be prepared to have deep discussions about real-world problem-solving, project portfolios, and experiences.

In MVC, we can easily apply validation to the web application by using Data Annotation attribute classes to the model class. When the routing engine finds a match in the Route table for the incoming URL, then it forwards that request to the appropriate controller and action method. If there is no match found in the Route table, then it returns a 404 HTTP status code.

The first parameter is the link text, and the second parameter is the name of the controller action. This route pattern is registered via a call to the MapRoute() extension method of RouteCollection. There are two types of routing (after the introduction of ASP.NET MVC 5). Routing is a mechanism to process the incoming URL that is more descriptive and gives the desired response. In this case, URL is not mapped to specific files or folder as was the case of earlier days web sites.

What is the difference between 3-tier Architecture and MVC Architecture?

ViewModel can bind a strongly typed view using its plain class with properties. It can also have well-defined validation rules for its various properties using the data annotation. Model logic is an essential part of the application that handles the logic for the application data. Visual Web Developer has created an Account folder, a Home folder, and a Shared folder (inside the Views folder). The Account folder contains pages for registering and logging in to user accounts. The Home folder is used for storing application pages like the home page and the about page.

It has been around for quite some time and provides a large set of libraries and APIs, making it suitable for developing complex enterprise-level applications. However, its monolithic nature makes it less flexible compared to .NET Core. Keeping pace with the ever-evolving world of technology is essential for any developer. This demonstrates your enthusiasm for the field and ensures you’ll bring the most current and efficient solutions to the team. My experience includes creating and cloning repositories, branching and merging code, resolving conflicts, and using pull requests to review and integrate changes from different contributors.

I add an error message on ModelState with a key and that message will be shown on the view whenever the data is not to be validated in the model. So, we can advantage of the “Output Caching” that avoids executing database queries each time the user invokes the controller method. Here the view page is retrieved from the cache instead of invoking the controller method and doing redundant work.

  • When it comes to software development, particularly as a .NET developer, integrating third-party libraries and APIs can be a significant part of the job.
  • Common Senior .net Developer interview questions, how to answer them, and example answers from a certified career coach.
  • Angular JS – It would be even better if you select a developer that has well-established practice on Angular JS.
  • The Result filters are executed before or after generating the result for an action.

Your experience with these platforms demonstrates your ability to adapt to modern development practices and showcases your versatility in working with various technologies. This can be a valuable asset in today’s fast-paced tech landscape. Once I can reliably replicate the problem, I use a combination of tools such as Visual Studio’s debugger, logging mechanisms, and performance profilers to narrow down the root cause. I also leverage my knowledge of the application architecture and codebase to identify potential areas where the issue might originate. During this process, I pay close attention to any recent changes that could have introduced the problem.
