I just published a new article about a question that we see once in a while in forums and I also needed to do in the last few weeks: How to download a file from a HTTPS site?
Luckily, .Net has everything we need. No special 3rd party library are required.
The reason I had to execute code like this was to download the status of some backups from CrashPlan Pro – a useful cloud-backup provider which I have been personally using for quite some time (notice that I don’t get any benefits from them!).
This is exactly the content of my September article that you can read from http://emoreau.com/Entries/Articles/2017/09/Downloading-files-from-HTTPS.aspx
