An unhandled exception of type 'System.TypeLoadException' occurred in Unknown Module

I have recently updated a legacy compact framework application to support Windows Mobile 6.5 but after going through my backwards compatability testing I have an issue with the WinCE 5 device.

When attempting to run the application from both the EXE and the debugger I get the "An unhandled exception of type 'System.TypeLoadException' occurred in Unknown Module." exception but its not giving me any idea which dll / type it has issue with.

The changes do work on the Windows Mobile 6.5 Motorola device and the Pocket PC 2003 Psion Device but not on the WinCE5 Psion device.

Does anyone have any ideas how I can find out which reference is causing me the issue. I have tried removing the new references to the Symbol barcoding and imaging libraries but I am still getting the same error.

Thanks,

Phil

UPDATE: OK, it looks like the .Net Compact Framework installation had corrupted some how. I flattened the device, reinstalled and everything appears to be working.

Do you have a reference to the Micrsoft.WindowsMobile assembly in the app? If so this will cause a failure (though I'm not 100% certain what the failure would look like, as I've not tried it in a long time). The WindowsMobile functionality is in an assembly that is already present on WinMo devices (so not part of the CF that is deployed by Studio), so a TypeLoadException wouldn't surprise me.
