Are you ready to leap from .NET Web Forms to Blazer? If so, congratulations! Blazor is a modern and exciting framework that allows you to build interactive web applications using C# instead of JavaScript. This step-by-step guide will walk you through migrating from .NET Web Forms to Blazor.

Step 1: Install the Necessary Software and Tools

The first step in the migration process is to set up your development environment for Blazor. This includes installing the necessary software and tools. Here's what you need to do:

  1. Install Visual Studio 2019: Blazor is fully supported in Visual Studio 2019, so install it on your machine. You can download Visual Studio 2019 from the official Microsoft website.

  2. Install the .NET Core SDK: Blazor requires the .NET Core SDK to be installed. You can download the latest version of the .NET Core SDK from the official Microsoft website.

  3. Install the Blazor Templates: Once the .NET Core SDK is installed, you can use the command-line interface (CLI) to install the Blazor templates. Open a command prompt and run the following command: dotnet new -i Microsoft.AspNetCore.Blazor.Templates

Once you have completed these steps, you can start building Blazor applications!

Step 2: Create a New Blazor Project

Now that your development environment is set up, it's time to create a new Blazor project. Here's how you can do it:

  1. Open Visual Studio 2019: Launch Visual Studio 2019 and click "Create a new project" on the start page.

  2. Select the Blazor App template: In the "Create a new project" dialog, search for "Blazor" and select the "Blazor App" template.

  3. Configure your project: Choose a name and location, and click "Create." In the project configuration dialog, select ".NET Core" as the target framework and choose the hosting model that suits your needs.

  4. Click on "Create." Once you configure your project, click "Create" to generate the initial project structure.

Congratulations! You have successfully created a new Blazor project. You can now start exploring the project structure and building your application.

Step 3: Migrate Your Existing Code

Now comes the exciting part - migrating your existing code from .NET Web Forms to Blazor. Here are some tips to help you with the migration process:

  • Start with a minor feature: Choose a little feature from your existing Web Forms application and try implementing it in Blazor. This will help you become familiar with Blazor syntax and concepts.

  • Refactor your code: As you migrate your code, take the opportunity to refactor it and make it more modular and maintainable. Blazor encourages using components, so break your code into reusable components.

  • Use Blazor-specific features: Blazor offers a range of features unavailable in Web Forms. Take advantage of these features to enhance your application. For example, you can use data binding, event handling, and routing in Blazor.

  • Test your code: Thoroughly test your migrated code to ensure it works as expected. Blazor provides a rich set of testing tools that you can use to write unit tests for your components.

Remember, migrating from .NET Web Forms to Blazor is not a one-to-one conversion. It requires effort and learning, but the benefits are well worth it. Blazor offers improved performance, scalability, and a more modern development experience.


This step-by-step guide covers the first steps in migrating from .NET Web Forms to Blazor. We have walked you through setting up your development environment and creating a new Blazor project. We have also provided some tips to help you with the migration process.

Now that you have a solid foundation, it's time to dive deeper into Blazor and explore its full potential. Happy coding!
