Blazor is a web framework developed by Microsoft that allows you to build interactive client-side web UIs using .NET and C# instead of JavaScript. It combines the flexibility of JavaScript with the power of .NET to provide a productive and efficient development experience.<\/p>\n

In this tutorial, we will walk through the process of creating a web app with ASP.NET Core and Blazor. We will cover the following steps:<\/p>\n

\n
1. Setting up the development environment<\/li>\n
2. Creating a new ASP.NET Core project<\/li>\n
3. Adding Blazor support to the project<\/li>\n
4. Creating a simple Blazor component<\/li>\n
5. Using the component in a Blazor page<\/li>\n
6. Running the Blazor app<\/li>\n<\/ol>\n

   Let’s get started!<\/p>\n

   1. Setting up the development environment<\/h2>\n

   Before you can create a web app with ASP.NET Core and Blazor, you need to set up your development environment. Here are the requirements:<\/p>\n

   \n
   • .NET Core SDK<\/a> (version 5.0 or later)<\/li>\n
   • A code editor (such as Visual Studio Code or Visual Studio)<\/li>\n<\/ul>\n

     Make sure you have the .NET Core SDK installed on your machine. You can verify the installation by running the following command in your terminal or command prompt:<\/p>\n

     dotnet --version\n<\/code><\/pre>\n
     If the command displays the version of the .NET Core SDK installed, you’re good to go.<\/p>\n
     2. Creating a new ASP.NET Core project<\/h2>\n
     To create a new ASP.NET Core project, open your terminal or command prompt and navigate to the directory where you want to create the project.<\/p>\n
     Run the following command to create a new ASP.NET Core project:<\/p>\n
     dotnet new webapp -o MyWebApp\n<\/code><\/pre>\n
     This command creates a new ASP.NET Core project named “MyWebApp” in a directory called “MyWebApp”. You can replace “MyWebApp” with any name you prefer.<\/p>\n
     Navigate into the project directory:<\/p>\n
     cd MyWebApp\n<\/code><\/pre>\n
     3. Adding Blazor support to the project<\/h2>\n
     To add Blazor support to the project, run the following command in your terminal or command prompt:<\/p>\n
     dotnet new blazorserver\n<\/code><\/pre>\n
     This command adds the necessary NuGet package references and files to enable Blazor in your ASP.NET Core project.<\/p>\n
     4. Creating a simple Blazor component<\/h2>\n
     Blazor components are the building blocks of a Blazor app. They are similar to Razor views in traditional ASP.NET MVC applications.<\/p>\n
     To create a simple Blazor component, open the project in your code editor and navigate to the “Pages” folder located in the “Areas” folder. This folder contains the Blazor pages of your app.<\/p>\n
     Create a new file called “Counter.razor” and add the following code:<\/p>\n
     @page \"\/counter\"\n\n<h1>Counter<\/h1>\n\n<p>Current count: @_count<\/p>\n\n<button class=\"btn btn-primary\" @onclick=\"IncrementCount\">Increment<\/button>\n\n@code {\n    private int _count = 0;\n\n    private void IncrementCount()\n    {\n        _count++;\n    }\n}\n<\/code><\/pre>\n
     This code creates a simple Blazor component called “Counter”. It displays the current count and provides a button to increment the count.<\/p>\n
     5. Using the component in a Blazor page<\/h2>\n
     To use the “Counter” component in a Blazor page, open the “Index.razor” file located in the “Pages” folder.<\/p>\n
     Replace the existing code with the following:<\/p>\n
     @page \"\/\"\n@inherits LayoutComponentBase\n\n<h1>Hello, Blazor!<\/h1>\n\n<Counter \/>\n<\/code><\/pre>\n
     This code sets the default route for the page to “\/”, inherits from the “LayoutComponentBase” class, and adds the “Counter” component inside the page.<\/p>\n
     6. Running the Blazor app<\/h2>\n
     To run the Blazor app, navigate to the project directory in your terminal or command prompt:<\/p>\n
     cd MyWebApp\n<\/code><\/pre>\n
     Run the following command to start the app:<\/p>\n
     dotnet run\n<\/code><\/pre>\n
     Open your web browser and navigate to `https:\/\/localhost:5001` to see the running Blazor app. You should see the “Hello, Blazor!” heading and the “Counter” component.<\/p>\n
     Click the “Increment” button in the component to see the count increase.<\/p>\n
     Congratulations! You have created a web app with ASP.NET Core and Blazor. You can now explore more features and build more sophisticated applications using Blazor’s powerful capabilities.<\/p>\n
     Conclusion<\/h2>\n
     Blazor provides an efficient way to build interactive client-side web UIs using .NET and C#. With its familiar programming model and powerful capabilities, you can create web apps that are both productive and performant.<\/p>\n
     In this tutorial, we walked through the process of creating a web app with ASP.NET Core and Blazor. We covered the steps of setting up the development environment, creating a new ASP.NET Core project, adding Blazor support, creating a simple Blazor component, using the component in a Blazor page, and running the Blazor app.<\/p>\n
