Deploying An Application with ClickOnce
deploying an application with ClickOnce
Gives you an easy way to detect and install prerequisites

Lets the user choose between per-user or per-machine installation

Allows you to deploy to a web server for windows installer projects

You can easily deploy your application from a website, fileshare, network or FTP location

You can install the application locally or run from the website

Two deployment models:

  • install
    • supports online and offline usage
    • Copies application files to user’s machine and installs
    • Makes entry to Start Menu of current user
  • Run from a network resource
    • Online only usage
    • Caches the application locally

Three ways to do application updates:

  • check for updates on startup
    • looks for updates before launching
    • if update is available the user can download and install
    • Makes the application take longer to load
  • check for updates after startup
    • launches application first
    • then checks for update periodically in the background
    • If upgrade available it downloads and installs the next time the user starts the application
    • You can specify a time interval to check for updates
  • custom logic
    • You can include a menu item to check for updates
    • Can install updates based on some business logic

ClickOnce allows you to roll back the last upgrade

If the application is run from online only it always runs the latest version
Upgrades can be required
Required upgrades can not be rolled back
