I wanted to retrieve contacts from Yahoo or any third party CARDDAV supported mail servers using CARDDAV protocol. I found the .NET Code to retrieve the contacts using CARDDAV on the link https://github.com/Metric/CardDavNet. I am trying to get the Yahoo and Google contacts using the URI:
https://www.googleapis.com/carddav/v1/principals/userEmail/lists/default
I made some requests using PROPFIND but getting empty address book. I think I am quite close but may be missing something.
Any help appreciated!
