Windows Mobile 5 on Smartphone

If you try to run a .NET Compact Framework 2.0 application on Windows Mobile 5 Smartphone (ie no touch screen), you may get an error like this:

NotSupportedException at Microsoft.AGL.Common.MISC.HandleAr()

This is because Windows Mobile 5 actually comes in two 'editions' - Smartphone and PocketPC. Whether they're actually the same codebase I don't know, but depending on your device different functionality is supported. For example - the PocketPC menus you can build in the Mobile 5 SDK don't work on Smartphones.

So if you have an app with that error, either bug the software publisher to get a Smartphone version written with the simpler menus, or go buy a PocketPC phone with touch screen.

And if you're wondering - I have an Orange SPV C600 which is only the Smartphone version of WM5 :)
