How to update the .NET CF into My WinCE device?

Question

I'm developping an application for Motorola MC3000 that use WinCE 5.0.

It seems that the machine is using the .NET CF 2.0, I just want to update it to .NET CF 3.5 but I don't know how to do it on the machine.

Any help on this?

The .NET Compact Framework installs side-by-side. You can simply copy the CAB file to the device, and run it. On your PC, you will find it at %ProgramFiles%\Microsoft.NET\SDK\CompactFramework\v3.5\WindowsCE\NETCFv35.wce.armv4.cab.

If you need it to be reinstalled on a cold boot (user pressed 1 + 9 + power, or left the battery out for too long) you will need to write some code to reinstall it. See the documentation for wceload for silent installation, and see Motorola's StartUpCtl for a way to control the order that things are run at start-up.

Some of Motorola's Windows Mobile devices had updates to allow the ROM version of .NET Compact Framework to be updated - for example the MC70 from 1.0 to 2.0 - but I'm not aware of any that had updates to replace it with 3.5.
