Hi,
you can use it only in the device. you have to start the setup exe and it
will copy the .net cf core libraries in the folder where u have opted to
install the application. At that time if a device is connected to desktop
thru active sync, it installs the .net cf core libraries in the device via
activesync. u can also manually take the respective cab files, copy to
device/emulator and execute them.
HTH,
Girish.
