Where has the CSOM online documentation gone?

Hello,

I am heavily using Powershell and Sharepoint CSOM, and used to refer to the online documentation available on MSDN.

For example, if I was looking for something about Microsoft.Sharepoint.Client.ClientContext, I could find it here: https://msdn.microsoft.com/en-us/library/microsoft.sharepoint.client.clientcontext_members.aspx

Now, most of the pages are redirected to the Microsoft.SharePoint.Client Namespace (https://docs.microsoft.com/en-us/dotnet/api/microsoft.sharepoint.client?redirectedfrom=MSDN&view=sharepointpnpcoreonline-2.18.1709.0) where I can't find any of the classes I use.

Any idea of what happened to these pages?

Thank you!
