Since a few people have asked me the same question through various channels and the answer is not straightforward, I created a thread to track the discussion. I've been recently asked whether ODP.NET Core ODP.NET Core supports LDAP.
The current answer is no, which is what you will find in the ODP.NET Core beta documentation. .NET Standard does not support System.DirectoryServices, which means ODP.NET Core does not support it either. However, MS has released the Windows Compatibility Pack (WCP), which does support System.DirectoryServices on Windows only. No cross platform support, but gives you LDAP support if running on Windows.
My question to ODP.NET Core users is whether you are looking for LDAP support for Windows only via WCP or you really want LDAP for Linux?
