Building a Blazor App in 2025

Getting Started

To start building a Blazor app, you need to have the .NET SDK installed on your machine. You can download it from the official .NET website.

Creating a New Blazor Project

Once you have the .NET SDK installed, you can create a new Blazor project using the following command:

dotnet new blazor -o Website

Running Your Blazor App

After creating your Blazor project, navigate to the project directory and run the following command to start the development server:

dotnet watch --project "PathTo.csproj"

Building Your First Component

Blazor apps are built using components. A component is a self-contained piece of UI that can be reused throughout your application. To create a new component, you can add a new Razor file in the Pages directory.

@page "/my-component"
    <h3 class="text-2xl font-bold">My First Component</h3>
    <p>This is my first Blazor component!</p>

Deploying Your Blazor App

Once you have built your Blazor app, you can deploy it to a web server or a cloud service. Blazor apps can be hosted on any web server that supports static files, such as IIS, Apache, or Nginx.

Conclusion

In this post, we covered the basics of building a Blazor app in 2025. Blazor is a powerful framework that allows you to build interactive web applications using C#. With its component-based architecture, you can create reusable UI components and easily manage the state of your application.

Installing Tailwindcss

To install Tailwind CSS in your Blazor project, you can follow these steps:

Navigate to the tailwind site and download the standalone executable. Get Tailwind Cli

Once you have the executable, you can run the following command in your project directory:

tailwindcss init

This will create a tailwind.config.js file in your project directory, which you can use to customize your Tailwind CSS configuration.

    module.exports = {
    content: [
        './Components/**/*.razor',
        './wwwroot/**/*.html'
    ],
    theme: {
        extend: {},
    },
    plugins: [],
    }
        

You need to create the css input file and add the following line.

@import 'tailwindcss';

After that, you can run the Tailwind CLI to generate your CSS file:

tailwindcss -i ./wwwroot/css/input.css -o ./wwwroot/css/output.css --watch

This command will watch for changes in your input CSS file and generate the output CSS file with Tailwind styles.
