DownloadHadError hook is not working in Windows Operating system

DownloadHadError event is not working and not triggering in windows operating system when there is no connectivity etc.
But this is working in MAC which is quite wierd.

Hi @balaji222528,

Thanks for your report. I appreciate it.

Just to be clear, what version of the library are you using on Windows, and what version of .NET are you using?

Thanks!

Iam using .net 8 and netsparkle 2.3.0

On 2.3.0:

The docs for this event say, Called when the download of an app cast file **has downloaded** but has an error other than corruption (emphasis mine). In other words, if the app cast file never downloads, this event is not guaranteed to be called.

This event is not meant to be triggered when there is no download at all. Furthermore, I cannot replicate the DownloadHadError event being called on 2.3.0 on macOS.

If you are getting here through a call to CheckForUpdatesQuietly, monitor the UpdateCheckFinished event. The status will be UpdateStatus.CouldNotDetermine if the download failed outright.

If you are getting here through a call to CheckForUpdatesAtUserRequest, UIFactory?.ShowCannotDownloadAppcast is called.

If this does not help, please upload a reproducible sample.

Thanks!
