Thid command should output:


Create a New C# Project

First, let’s create a new C# Blazor project. Open your terminal and run the following commands:

dotnet new blazorwasm -o NameOfYourProject

This will create a new Blazor project in a directory named NameOfYourProject. The directory contains by default an example project for you to play around. To get into more details read this tutorial from the official microsoft website:

To run the project locally navigate into the project folder:

cd NameOfYourProject

Use this command to start up the local development server:

dotnet watch

It even has hot reloading!

Build your Project for Deployment

To deploy your C# application to Vercel, you need to build it first on your machine. Use this command to generate the output files.

dotnet publish -c Release

The output files will be located in this folder:


Please note that the exact path my vary a bit. Depending on your .NET version.

Initialize a Git Repository

Next, initialize a new Git repository and commit your code:

git init
git add .
git commit -m "Initial commit"

No push the code to your git repository. First connect the github repo to your local repository:

git remote add origin https://github.comXXXXX
git push origin master

Deploy to Vercel

Now, it’s time to deploy your application to Vercel. Follow these steps:

  1. Go to Vercel
  2. Add New Project
  3. Select the repository from your github account
  4. Set custom Build & Development Settings
  5. Override the Output Directory to: bin/Release/net8.0/publish/wwwroot

Thats it! You should now see a preview of your deployed C# Blazor App.

If you want to publish changes follow these instructions:

  1. bash dotnet publish -c Release
  2. git add . && git commit -m "Your Commit Message"
  3. git push origin master

Vercel will take care of the rest and you should see the live changes in 1-2 minutes on your website.
