Say WCF inside is using winsock? Just wondering.

    1 answer 1

    Partially uses.

    All client channels are built on top of Winsock.

    HTTP server channels use the HTTP.SYS driver, which does not use Winsock (it directly uses the network kernel stack).

    Server Net.Tcp channels can use Winsock if the postSharingEnabled setting is disabled. In the port sharing mode, the network part is delegated to a separate service, but the application does not use Winsock directly.
