ASP.Net MVC has an attribute called “HandleError” that provides built-in exception filters. The HandleError attribute in ASP.NET MVC can be applied over the action method as well as Controller or at the global level.

And this can actually decrease the application performance.

ASP.Net MVC is a pattern which is used to split the application’s implementation logic into three components i.e. models, views, and controllers. Scaffolding is a code generation framework for ASP.NET Web applications. Visual Studio includes pre-installed code generators for MVC and Web API projects. You add scaffolding to your project when you want to quickly add the code that interacts with data models. Using scaffolding can reduce the amount of time to develop standard data operations in your project.

  • However, you can use your own specific programming languages, including Ruby on Rails, .NET, Java, amongst others, for solving MVC interview questions.

If we want “TempData” to be read and also available in the subsequent request then after reading we need to call “Keep” method as shown in the code below. ViewBag is also used to pass data from the controller to the respective view. It is a component that keeps consistency between the abstraction within the system and their presentation to the user.

By using the MVC framework mvc developer we can design pluggable and extensible components which can be replaced or customized easier than Web Forms. To manage the complex application, MVC design pattern divides the ASP.NET MVC application into Model, View and Controller. You can work as an MVC developer even with a bachelor’s degree and upgrade your skills.
