The core class library reference for SharePoint 2013 lists .NET server namespaces. These namespaces contain classes and other members that are designed mainly to help you develop solutions for SharePoint end users and low-level administrators, such as site owners.
For information about classes that run on a client, see .NET client API reference for SharePoint 2013.
