Location of Microsoft.Sharepoint.dll in SharePoint 2013 and SharePoint 2016

Sometimes if you want to work with SharePoint server object model then you need to refer to Microsoft.SharePoint.dll. Similarly if you want to work with .Net client object model then you need to refer to Microsoft.SharePoint.Client.dll.

The dll is available in the ISAPI folder in the SharePoint installation directory.

SharePoint 2016:
Both Microsoft.SharePoint.dll and Microsoft.SharePoint.Client.dll will be available in the below directory. Here I have installed SharePoint in C drive.
