Use WCF to Control Your Toys
Cohesive Computing have ported Microchip's TCP/IP stack v5 to the Pic Mini Web board by Olimex. This adaptation supports Http and Ftp, and is able to process Http Get requests and provide responses in JSON and other formats.
Included as part of the demo application is a WCF .net client that consumes example web services programmed on the board, and documentation is included explaining how to run the demo and develop your own web services for the board.
Of course, you'll need to have your own Mini Web board and PIC® programmer, and will need to download MPLAB and C18 compiler to develop your own web services.
