I am looking to setup a CardDAV server which will sync my contacts from a database to a client device using a standard protocol.
I am currently using ASP.net for web and MSSQL 2008 for the backend, now I want to develop an access point where the user can directly add a server url and authentication details to sync the contacts.
I am looking for a CardDAV server which will work with my current setup. Please help me to find the standard solution, all the current CardDAV servers are in PHP and MySQL .
