I developed a transit system (initial development, when practice)
Sdf database format used (sqlce)
It can run on top of my PDA

However, I want to develop a Windows program that can manage database sdf file.
But I have the following Windows platforms, you can not connect to sdf file, tips can not be loaded sqlceme30.dll file
I copy the file to the PC windwos \ system32 or exe under the same directory, it is invalid ah

Will C # how to manage the Windows platform sqlce database files sdf?
