HappyBin is an auto-updater for .NET apps. It is designed as an api, and can be used as a boot-strap or a passive updater. Every app deserves a HappyBin!

HappyBin AutoUpdater is designed to be a compiled exe that sits next your primary application. When launched, the auto-updater will check a Http/Ftp/UNC for an update config file, compare the advertised version with the current version of your exe, download a zip, extract the files to apply the update, and then (re-)launch your exe. This process can run as a boot-strap or passive/background (see below) to suit your needs. Either way, the integration with your code is absolutely minimal, requiring, at most, one line of code, and no dependencies.

You can use the autoupdater as-is with no modifications, or you can customise the UI or the update workflow. The Updater class presents four public methods to download and install updates, and the MainDlg implements a typical update workflow. Change either to your liking.

• Boot-strap: Runs ahead of primary application and downloads/installs patches. This mode requires no code changes to your primary application.
• Passive/Background: Runs after app launch and silently downloads updates; prompts for install. This is designed in the style of Firefox/Chrome updates and requires only a Process.Start call from your primary application.
• AboutBox: Runs at user discretion; prompts for install. This is designed in the style of Firefox/Chrome updates and requires only a Process.Start call from your primary application.

• Update files are maintained as zips, downloaded, and then unzipped to the target folder.
• Supported download protocols are: Http, Ftp, and UNC.
• HappyBin will also delete files from the target folder.

• Release notes dialog.
