Hi Schneider,

A desktop assembly cannot execute on the device, but the reverse is
possible. If you create a smart device project and build it, the output
(the EXE or DLL) can be executed on the desktop and can be referenced by
desktop projects.

This works because the .NET Compact Framework assemblies are retargetable.
If you open one of them with ILDASM, you can observe that they have the
System.Reflection.AssemblyNameFlags.Retargetable attribute. This means that
at run time all references to the .NET Compact Framework assemblies are
retargeted to the desktop equivalents. So, to be clear, your assembly uses
the desktop implementation, not the device implementation of the .NET
Framework.

Note that the .NET Compact Framework is not a strict subset of the .NET
Framework; it actually adds some members of its own. There are four
device-specific assemblies: System.Data.SqlServerCe, System.Net.IrDA,
Microsoft.WindowsMobile.DirectX and Microsoft.WindowsCE.Forms.

If an assembly built with the .NET Compact Framework uses a device-specific
type, when it is executed on desktop, an exception will be thrown.

For more information about sharing code between full .NET Framework and
Compact Framework, please refer to the following article:

Hope this helps.

Yes, I have ran PPC apps on the desktops before, thought it's not as nice as
a full Windows app.

In my case it's a set of custom windows controls, which in theory should
work on CE, PPC, ...
I do have the controls logically separated also, Abstract Interfaces,
Business logic, Rendering logic, and testing application, so I would think
it should be easier to convert.
