Velopack is a setup / installation framework for cross-platform dotnet applications. Great out-of-the-box development experience, with zero configuration or setup needed. Lightning fast to use, and lightning fast for your users, too.

Features

• 😍 Zero config – Velopack takes your dotnet build output (eg. dotnet publish), and generates an installer, and updates and delta packages in a single command.
• 🎯 Cross platform – Velopack supports building packages for Windows, OSX, and Linux. No matter your target, Velopack can create a release in just one command.
• 🚀 Automatic migrations - If you are coming from Squirrel.Windows or Clowd.Squirrel, Velopack will automatically migrate your application. Just build your Velopack release and deploy! Read more.
• ⚡️ Lightning fast – Velopack is written in Rust for native performance. Creating releases is multi-threaded, and produces delta packages for ultra fast app updates. Applying update packages is highly optimised, and often can be done in the background.

Getting Started

This is a very simple example of the steps you would take to generate an installer and update packages for your application. Be sure to read the documentation for an overview of more features!

1. Install the command line tool vpk:

   dotnet tool update -g vpk
   

2. Install the Velopack NuGet Package in your main project:

   dotnet add package Velopack
   

3. Configure your Velopack app at the beginning of Program.Main:

   static void Main(string[] args)
   {
       VelopackApp.Build().Run();
       // ... your other startup code below
   }
   

4. Publish dotnet and build your first Velopack release! 🎉

   dotnet publish -c Release --self-contained -r win-x64 -o .\publish
   vpk pack -u YourAppId -v 1.0.0 -p .\publish -e yourMainApp.exe
   

5. Add automatic updating to your app:

   private static async Task UpdateMyApp()
   {
       var mgr = new UpdateManager("https://the.place/you-host/updates");
   
       // check for new version
       var newVersion = await mgr.CheckForUpdatesAsync();
       if (newVersion == null)
           return; // no update available
   
       // download new version
       await mgr.DownloadUpdatesAsync(newVersion);
   
       // install new version and restart app
       mgr.ApplyUpdatesAndRestart();
   }
   

If you're not sure how these instructions fit into your app, check the example apps for common scenarios such as WPF or Avalonia.

Testimonials

I have now got my external facing application using velopack. I am very impressed. Seems to work fabulously well and be much faster both in the initial build and in the upgrading of the software on the end user's machine than Squirrel was. It's amazing and the best installer I've ever used in over 30 years of development. Thanks so much! You are doing some great work! - Stefan (Discord)
