Notes about the APPLICATION file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The APPLICATION file type is primarily associated with 'ClickOnce' by Microsoft Corporation. ClickOnce is a Microsoft technology for deploying Windows Forms or Windows Presentation Foundation-based software, also called Smart clients. It is similar to Java Web Start for the Java Platform. ClickOnce is only available in .NET 2.0 and later.
