Softtek Most Frequently Asked ASP.NET MVC Interview Questions Answers
What Is Dependency Injection In Asp.net Mvc?
it's a design pattern and is used for developing loosely couple code. This is greatly used in the software projects. This will reduce the coding in case of changes on project design so this is vastly used.
Explain The Advantages Of Dependency Injection (di) In Asp.net Mvc?
Below are the advantages of DI
Reduces class coupling
Increases code reusing
Improves code maintainability
Improves application testing
Does Tempdata Hold The Data For Other Request In Asp.net Mvc?
If Tempdata is assigned in the current request then it will be available for the current request and the subsequent request and it depends whether data in TempData read or not. If data in Tempdata is read then it would not be available for the subsequent requests.
Explain Keep Method In Tempdata In Asp.net Mvc?
As explained above in case data in Tempdata has been read in current request only then "Keep" method has been used to make it available for the subsequent request.
@TempData["TestData"];
TempData.Keep("TestData");
Explain Peek Method In Tempdata In Asp.net Mvc?
Similar to Keep method we have one more method called "Peek" which is used for the same purpose. This method used to read data in Tempdata and it maintains the data for subsequent request.
string A4str = TempData.Peek("TT").ToString();
What Is Area In Asp.net Mvc?
Area is used to store the details of the modules of our project. This is really helpful for big applications, where controllers, views and models are all in main controller, view and model folders and it is very difficult to manage.
How We Can Register The Area In Asp.net Mvc?
When we have created an area make sure this will be registered in "Application_Start" event in Global.asax.
Below is the code snippet where area registration is done
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
}
What Are Child Actions In Asp.net Mvc?
To create reusable widgets child actions are used and this will be embedded into the parent views. In ASP.Net MVC Partial views are used to have reusability in the application. Child action mainly returns the partial views.
Explain Test Driven Development (tdd) ?
TDD is a methodology which says, write your tests first before you write your code. In TDD, tests drive your application design and development cycles. You do not do the check-in of your code into source control until all of your unit tests pass.
Explain The Tools Used For Unit Testing In Asp.net Mvc?
Below are the tools used for unit testing
NUnit
xUnit.NET
Ninject 2
Moq
What Is Representational State Transfer (rest) Mean?
REST is an architectural style which uses HTTP protocol methods like GET, POST, PUT, and DELETE to access the data. ASP.Net MVC works in this style. In ASP.Net MVC 4 there is a support for Web API which uses to build the service using HTTP verbs.
How To Return The Json From Action Method In Asp.net Mvc?
Below is the code snippet to return string from action method
public ActionResult TestAction() {
return JSON(new { prop1 = "Test1", prop2 = "Test2" });
}
How Does The 'page Lifecycle' Of Asp.net Mvc Works?
Below are the processed followed in the sequence
App initializWhat is Separation of Concerns in ASP.NET ASP.Net MVCation
Routing
Instantiate and execute controller
Locate and invoke controller action
Instantiate and render view.
Explain The Advantages Of Asp.net Mvc Over Asp.net?
Provides a clean separation of concerns among UI (Presentation layer), model (Transfer objects/Domain Objects/Entities) and Business Logic (Controller).
Easy to UNIT Test.
Improved reusability of model and views. We can have multiple views which can point to the same model and vice versa.
Improved structuring of the code.
What Is Separation Of Concerns In Asp.net Asp.net Mvc?
It is the process of breaking the program into various distinct features which overlaps in functionality as little as possible. ASP.Net MVC pattern concerns on separating the content from presentation and data-processing from content.
