When deploying a clickonce app using vs2008 over the .net 3.5 framework, I have added the following xml to the app manifest
(??? are used as representations, not the actual letters I use)
extension = ".???"
description = "??? Document"
progid = "???.Document"
as described in the MSDN.
When I attempt to deploy the app on a test machine the following error occurs during install:
"Cannot Continue, the Application is Improperly Formatted. Contact the application vendor for assistance."
reading through the details in the log we find:
File associations are not allowed in deployment manifest.
I should add that this is a full trust application, and we are currently using a test certificate.
According to MSDN this should be working. Any idea why it is not?
