ASP.NET migration involves moving your web application from Web Forms to the MVC framework. The MVC offers a cleaner separation of concerns and improved testability. This can make your application more maintainable and easier to scale in the long run. In this guide, we’ll explore how to convert ASP NET website to web application, its benefits, and essential resources.

Where and How to Start?

To convert ASP NET website to web application, you need an existing application, an IDE like Visual Studio with ASP.NET development capabilities, and an understanding of ASP.NET MVC concepts, which can be explained online through resources like the ASP.NET MVC Tutorial.

Some of the essential tools for a successful asp.net migration include the following: 

  • Visual Studio. This tool provides an environment to create, edit, and debug your MVC project.
  • ASP.NET MVC project template. This is a pre-configured template in Visual Studio that streamlines the MVC project setup.

A full migration may involve many steps. Before you start, think about the scope and intricacy of your application.

Migrating from the ASP.NET Webforms to ASP.NET MVC

The asp.net migration process has several vital steps. The combination and thorough implementation of these vital steps can lead to a smooth process and perfect results. Below is a step-by-step guide to convert asp.net web site to web application:

Step 1: Setting Up the MVC Project

To start the ASP.NET migration process, you have to do the following:

What to do:

  1. In addition to your current Web Forms project, create a new ASP.NET MVC project.

How to do: 

  1. Navigate to “File” > “New” > “Project” in Visual Studio. 
  2. When creating a project, pick “MVC” and the “ASP.NET Web Application (.NET Framework)” template.

Expected Result: 

As a result, you will have a new project with the basic MVC structure.

Step 2: Migrating Piece by Piece

Then, move to the next stage of the asp.net migration process:

What to do:

  1. Make a tiny, well-defined MVC migration to your Web Forms application first. This could be a single page or a feature.

How to do:

  1. Make a new MVC controller that will be in charge of managing user requests. 
  2. Establish the relevant model or models to describe your data. 
  3. Create views with Razor syntax to show the model’s data.

Expected Result: 

Thus, you will be able to use small sections of your Web Forms application in the new MVC project. Launching the MVC project and using the migrated functionality will allow you to test it.

Step 3: Iterative Migration and Testing

Now, you can start working with iterative ASP.NET migration:

What to do:

  1. Repeat the previous step to progressively transfer Web Forms functionality to MVC. 
  2. Make sure your migrated parts are functioning as intended by testing them frequently.

How to do: 

  1. Concentrate on transferring Web Forms event handler logic to MVC controllers. 
  2. Utilize model binding to add user input to models. 
  3. Test your views to guarantee correct data display and user interaction.

Expected Result: 

A larger and larger portion of your Web Forms application within the MVC project becomes functional as you iterate. Frequent testing aids in finding and resolving any problems that may arise throughout the move.

Step 4: Data Access and Business Logic

After that, proceed to structuring data access and business logic:

What to do:

  1. Transfer your business logic and data access layer (DAL) to the MVC application so that it functions properly.

How to do:

  1. In order to make your current data access code reusable across the MVC controllers, refactor it. 
  2. Make sure your business logic can work with the MVC application’s data models.

Expected Result: 

Your data access and business logic will function correctly within the context of your MVC project.

Step 5: Refactoring and Cleanup

This is the last stage of the asp.net migration process:

What to do:

  1. Refactor your code for efficiency, maintainability, and compliance with MVC best practices when the ASP.NET migration is finished.

How to do:

  1. Check your controllers for any possible duplication of code. 
  2. For testability, take into account employing dependency injection. 
  3. Eliminate any code or resources that aren’t being used in the Web Forms project.

Expected Result: 

You will have an organized, manageable MVC application that satisfies every feature of your initial Web Forms project.

Why Should I Upgrade to ASP.NET MVC

It is a smart choice to use ASP.NET MVC for code maintainability, testability, performance, flexibility, and search engine optimization advantages. Because of MVC’s obvious division of responsibilities, code is simpler to comprehend, alter, and debug. Its modular design simplifies unit testing, enhancing code quality and minimizing regressions.

MVC’s lightweight architecture improves application performance, particularly dynamic and sophisticated online apps. Additionally, it gives users more power over HTML syntax, which makes user interface design more adaptable. The more orderly division of responsibilities in MVC enhances SEO and produces more meaningful URLs. Its broader development community provides more support and resources.

ASP.NET Webforms to ASP.NET MVC Checklist

This checklist guides you through the process of migrating your ASP.NET Web Forms application to ASP.NET MVC:

  1. Preparation. Review the features of the Web Forms application, set up a Visual Studio development environment, and become familiar with the fundamentals of ASP.NET MVC.
  2. Migration process. Create a new project in ASP.NET MVC and move Web Forms functionality to MVC. Define data models and Razor views, apply data access and business logic, test the migrated functionality, and convert ASP.NET web site to web application and test the migrated portions in an iterative manner.
  3. Post-migration. Refactoring and optimizing code, using MVC best practices, eliminating superfluous code or resources, and assessing and revising documentation to align with the updated MVC architecture are all part of the process.

The size and complexity of your application determine the ASP.NET migration complexity. Examine carefully, take your time, and don’t be afraid to look for more information online.
