APPLICATION file extension - ClickOnce deployment manifest

What is application file? How to open application files?

The application file extension is associated with ClickOnce, a Microsoft's technology for deploying Windows Forms or Windows Presentation Foundation-based software, which is also called Smart clients. It is similar to Java Web Start for the Java Platform. ClickOnce is only available in .NET 2.0 and its later versions.

The application files contain a deployment manifest, a XML file that describes a ClickOnce deployment, including the identification of the current ClickOnce application version to deploy.

The application files were designed to provide easy "one click" deployments of user-level Windows applications. They have a corresponding .appref-ms file that activates the ClickOne for a program, which subsequently executes within the .NET framework in Windows.
