VS projects targeting .Net Compact Framework (CF) are different from projects targeting regular .Net. To show this difference we prefix all CF projects with "CF.". If you don't have the hardware for the sumo robot [1] you can use the simulated version as described in the README file for the sumo package.

Thanks for replying and the great link to build the robot.
my query still is how to get the program to work in my visual studio. Have installed/uninstalled VS 2005 and tried Express Edition as well as Team Edition but both have the same problem. Have also tried on a different computer in case it could be settings issue but the same problem as well.
I am thinking that maybe the wrong file was chosen as start-up. Is there a particular file that i have to select as start up for the program to work correctly?
If you have full VS then .Net CF works fine. What you see is not an actual problem; it is just that when developing for CF, VS asks you which device to target. If you have the actual hardware for a Sumo bot then the EBox CE device comes with a small MSI file that tells VS that it can be used as a target device for CF developement. Without that VS falls back on the ones that it already know about which is the list you see. Using something like the Windows CE 5.0 Device emulator should be fine.
