in the developer guide, is there a section discuss abt network configuration?

I know WCF is becoming porpular, but i notice Devforce doesn't use WCF in the app.config file, so how Devforce deal with the network communication between client and server? is it possible to use TCP in Devforce?is there a section in the developer guide that discusses abt the configuration of network?

As smi-mark said, DevForce EF uses only WCF for communications to a BOS.  Both http(s) and tcp are supported.  For a "vanilla" configuration the objectServer element in the ideaBlade section of the configuration file is all that's needed for configuring communications.  For more advanced configurations or to override default settings, you need to include a WCF serviceModel section in the configuration file.   Sample config files can be found in the SampleCode folder of your DevForce installation.
