How do we use the ProgID column in the File Associations settings?

Question

I\'m deploying my application using ClickOnce.

I want to register a file association but I can\'t manage to make it work: What should I use as ProgID

Answer 1

It's a name that uniquely identifies the file type. So a description might be "Document created with Microsoft Word" and the ProgID might be "Word". If your app name is short, you can just put that in there. If your app name isn't short, put in some abbreviation of it.
