The services section and client section under system.serviceModel in the configuration file refer to different aspects of a WCF application.

The services section is used to define the behavior of the WCF service itself. It defines the endpoints, bindings, and contracts that are used to expose the service to clients. This section also includes additional configuration settings for features like message security, error handling, and throttling.

The client section, on the other hand, is used to configure the behavior of the client that consumes the WCF service. It defines the endpoints and bindings that are used to connect to the service, and includes additional settings for features like message security and error handling.

In summary, the services section is used to define the behavior of the WCF service, while the client section is used to configure the behavior of the client that consumes the service.

 

 

The services section in the system.serviceModel configuration specifies the WCF services that are exposed to other clients to use, while the client section is used to specify the configuration for clients that consume external WCF services.

In other words, the services section is used to configure the behavior of the WCF service provider, while the client section is used to configure the behavior of the WCF service consumer.
