When it comes to application development within the Microsoft Stack, there are two popular frameworks: Asp.Net MVC and Web Forms.
Asp.net was developed a few years ago as a replacement for Classic ASP, and it featured Web Forms.
However, while Web Forms was acceptable for smaller projects, it proved to be difficult to scale for larger applications.
Specific pages and code tend to be tightly tied together and the heavy reliance on the server to handle events, control rendering also adds to reduced performance.
Asp.net MVC helps alleviate these issues by implementing the Model View Controller pattern.
The separation of the layers helps development by allowing applications to be more expandable, quicker to develop, and more organized long term when it comes to maintenance.
One of the first steps when converting a non-MVC asp.net site to an ASP.net MVC site is to define your Model, View, and Controller architecture.
Table of Contents
Model Layer
Starting with the Model layer, this begins with identifying the data elements used by the application.
These data objects would be retrieved by the controller layer and used in order to generate the view which is returned back to the user’s browser.
During this step, additional layers to work with the database are created.
This approach allows more flexibility in case of changes in the database.
In general, this can be done by analyzing the existing database, and in most cases, each table can be represented as a data model object.
Controller Layer
The Controller layer is responsible for managing user interactions with the application by responding to user requests and returning the appropriate updates made to the user’s view (browser).
At this step, we would analyze all the pages of the previous application and determine all actions and events that are required.
This includes preparing data to be displayed on page load, responding to button clicks whether saving data, page navigation, etc.
View/Presentation Layer
Through the separation of the code behind on each page, the View layer is now more free to be coded with more plain HTML code.
This can be done through the Razor markup which presents a more html like way of embedding code or even updating the view to use a more front-end framework like Angular.
During this step, web form pages will be stripped of the server side control code and focus on updating to contain only front end UI view code.
This results in view pages that are easier to update based on designs from Graphic Designers who may not be as familiar with working with or have direct access to the asp.net web form code.
Converting to the MVC pattern arranges the code in a more separate and organized fashion.
However, additional steps can be made to improve the sites performance, and overall organization even more.
Through the use of Javascript front-end frameworks like Angular and utilized ASP.net MVC Web.API framework. Using ASP.net MVC Web.api, controllers are now designed as more HTTP service.
Allowing more flexibility in responding to user actions and events.
This approach allows the view to be more independent, allowing the website to be more accessible, whether through web or mobile.
With these steps, we can help upgrade the existing site to be more expandable, quicker, and responsive to the client’s needs.
Conclusion
ASP.NET MVC and Web Forms are both popular for Microsoft Stack development, but Web Forms can be limiting for larger applications due to tightly coupled code and server reliance.
ASP.NET MVC addresses these issues by implementing the Model-View-Controller (MVC) pattern, enhancing scalability, organization, and maintenance.
The MVC approach divides the application into Model (data), Controller (user interactions), and View (presentation) layers, creating a cleaner, more flexible structure.
With additional tools like Angular and ASP.NET MVC Web API, applications become more responsive and accessible across devices.
This transition enables faster, more scalable, and client-responsive applications.
