If you are visiting ASP.NET forums and communities, you will find following questions frequently i.e.
- What is the difference between ASP.NET MVC and ASP.NET WebForms?
- Is ASP.NET MVC going to replace ASP.NET WebForms?
- ASP.NET MVC vs ASP.NET WebForms | ASP.NET WebForms Vs MVC model?
In this web development tutorial, We’ll try to answer and explain such queries.
First of all, let me clear that ASP.NET MVC is not replacing ASP.NET WebForms. Both these development models exist and can be used to develop ASP.NET applications. Although both has pros and cons, that we will discuss and compare here.
Before going into deeper details let’s have a high level comparison as:
***ASP.NET WebForms developers migrating to ASP.NET MVC initially feel a little uncomfortable because they are unable to find many key features that were available in WebForms approach. There are many questions comes to their minds like below:
- Web is still stateless but where is the Viewstate?
- Where is that Code behind file?
- What is that Razor syntax? Why I need it?
- Where to find Page_Load method? that is used to put code for almost every page.
- What about Binding and Rich Server Controls? Where these controls gone?
- and many more…
ASP.NET MVC vs ASP.NET WebForms
Following table explains the difference to answer above questions by clearly explaining the limitations of each approach.
ASP.NET Web Forms
ASP.NET Web Forms uses Page controller pattern approach for rendering layout. In this approach, every page has it’s own controller i.e. code-behind file that processes the request.
ASP.NET MVC uses Front Controller approach. That approach means ,a common controller for all pages, processes the requests.
No separation of concerns. As we discussed that every page (.aspx) has it’s own controller (code behind i.e. aspx.cs/.vb file), so both are tightly coupled.
Very clean separation of concerns. View and Controller are neatly separate.
Because of this coupled behavior, automated testing is really difficult.
Testability is key feature in ASP.NET MVC. Test driven development is quite simple using this approach. Please follow here for demo on building testable applications.
In order to achieve stateful behavior, viewstate is used. Purpose was to give developers, the same experience of a typical WinForms application.
ASP.NET MVC approach is stateless as that of the web. So here no concept of viewstate.
Statefulness has a lots of problem for web environment in case of excessively large viewstate. Large viewstate means increase in page size.
As controller and view are not dependent and also no viewstate concept in ASP.NET MVC, so output is very clean.
ASP.NET WebForms model follows a Page Life cycle.
No Page Life cycle like WebForms. Request cycle is simple in ASP.NET MVC model.
With a lots of control libraries availability and limited knowledge of other related technologies, ASP.NET WebForms is RAD(Rapid Application Development) approach.
It’s a step back. For developers decrease in productivity.
It’s good for small scale applications with limited team size.
It’s better as well as recommended approach for large-scale applications where different teams are working together.
This article explains the pros and cons associated with each model. And in last point, I concluded that which model is suitable in a scenario. Hopefully, it will be a reference for choosing the right approach.
- A. ViewResult
- B. ASPViewResult
- C. EmptyResult
- D. PartialViewResult
- E. RazorViewResult
