AutomaticUpdater Members

Allows you to add full control over how updates are checked, downloaded, and installed to your .NET app.

The AutomaticUpdater and AutomaticUpdaterBackend types exposes the following members. A few of the properties and events are specific to either the AutomaticUpdater type or the AutomaticUpdaterBackend type; we've made a note of such cases.

Arguments Gets or sets the arguments to pass to your app when it's being restarted after an update.
Changes Gets the changes for the new update.
ClosingForInstall Gets if this AutomaticUpdater has hidden this form and preparing to install an update.
