As a developer, you have lots of flexibility in specifying when and how update checks are performed, whether updates are mandatory, and where the application should check for updates. You can configure the application to check for updates automatically before the application starts, or at set intervals after the application starts.

In addition you can specify a minimum required version; that is, an update is installed if the user's version is lower than the required version. You can configure the application to check for updates programmatically based on an event such as a user request. The procedure "To check for updates programmatically" in this topic shows how you would write code that uses the ApplicationDeployment class to check for updates based on an event.

In order to update a ClickOnce application programmatically, you must specify a location for updates. This is sometimes referred to as a deployment provider.

For more information on setting this property, see Choose a ClickOnce update strategy. You can also use the technique described below to deploy your application from one location but update it from another. For more information, see How to: Specify an alternate location for deployment updates.

Create whatever button, menu item, or other user interface item you want your users to select to check for updates. Since the tools don't have ClickOnce integration I can't rely on starting them to run an update. I suppose I could just add another tool that can be manually run to force an update.
