Microsoft Application Updater Block

Nice feature from Microsoft, it is simple yet powerful.

What is Application Updater Block?

The Updater Application Block is a .NET component that you can use to detect, validate, and download application updates deployed in a central location. By using the Updater Application Block, you can keep desktop applications up to date with little or no user intervention. You can also extend the Updater Application Block to use custom classes for downloading and validating files, performing post-deployment configuration tasks, and controlling the update process.
