The title is the question by its own!
Can I program using SQL CE 4.0 for the Windows Mobile devices? Is there any runtime that I must install to develop software on the CE 4? or it just can play using the ADO.NET API?
Thank you.
No:
Compact 4.0 does not have a release for Windows Mobile, Windows Phone or for Windows CE devices.
Compact 3.5 SP2 is the latest version supported on Windows Mobile
