Running and Deploying Your Blazor Application: A Comprehensive Guide

Introduction

Blazor, a web framework by Microsoft, has gained tremendous popularity among developers for its ability to build interactive web applications using C# and .NET. Once you’ve developed your Blazor application, the next critical step is running and deploying it to make it accessible to users worldwide. In this article, we’ll walk you through the process of running your Blazor application locally and deploying it to a web server.

Running Your Blazor Application Locally

Before deploying your Blazor application, you should run it locally to test its functionality and ensure everything works as expected. Here are the steps to run your Blazor application on your local machine:

1. Install .NET Core: If you haven’t already, make sure you have .NET Core (or .NET 5+ since .NET Core has been merged into .NET 5) installed on your development machine. You can download it from the official .NET website.
2. Open Your Blazor Project: Navigate to your Blazor project’s directory using the command line, or open it using your preferred code editor. Visual Studio and Visual Studio Code are excellent choices for Blazor development.
3. Build the Project: In the command line, navigate to your project’s directory and use the following command to build your Blazor application:

   dotnet build

4. Run the Project: To run your Blazor application locally, use the following command:

   dotnet run

This will start a development server, and your Blazor application will be accessible at https://localhost:5001 or http://localhost:5000 by default. You can open your web browser and navigate to this URL to view and interact with your application.

Deployment of Your Blazor Application

Once you are satisfied with the local performance of your Blazor application, it’s time to deploy it to a web server for the world to access. Here’s a step-by-step guide to deploying your Blazor application:

1. Choose a Hosting Service: You can deploy your Blazor application to various hosting services, including Azure, AWS, GitHub Pages, or traditional web hosts like Bluehost and GoDaddy. The choice depends on your requirements, budget, and familiarity with the platform.
2. Publish Your Blazor Application: Before deployment, you need to publish your application, which prepares it for hosting. Use the following command to publish your Blazor application:

   dotnet publish -c Release

This command will create a publish folder with the necessary files to run your application.

3. Configure the Hosting Environment: The steps for configuring the hosting environment may vary depending on the hosting service you choose. Typically, you’ll need to set up the domain or subdomain, configure DNS settings, and set up the web server (if not handled by the host).
4. Deploy to the Hosting Service: The deployment process also varies depending on the hosting service. Here are some common methods:

• Azure: If you’re using Azure, you can deploy your application directly from Visual Studio using Azure App Service or use Azure DevOps pipelines.
• GitHub Pages: For simple, static Blazor applications, you can deploy to GitHub Pages directly from a GitHub repository.
• Traditional Hosting: If you’re using a traditional web host, you may need to use FTP or a control panel to upload your application’s files to the server.

3. Test Your Deployed Application: Once your Blazor application is deployed, test it thoroughly to ensure that it works as expected in the live environment. Address any issues that may arise during deployment.

Conclusion

Running and deploying your Blazor application is a crucial step in the software development process. By following the steps outlined in this article, you can ensure that your application is tested and accessible to users, providing them with the experience you’ve designed. Whether you’re deploying to a cloud platform, a static site host, or a traditional web server, a successful deployment is the culmination of your hard work in building a Blazor application.
