I tried to run the directx samples from ..\Windows Mobile 6 SDK\Samples\PocketPC\CPP\win32\directx\d3dm\tutorials on a Samsung Omnia and on the emulator and it doesn't work because of a deployment error.
I am using Microsoft Visual Studio 2008 and have installed Windows Mobile SDK Standard and Professional refresh.
The device is correctly plugged in and set up for active sync (I know this because other samples work, also a creating Win32 smart device application and running it works).
When I try to run a directx sample application it compiles without errors but the message:

" There were deployment errors, Continue? Yes/No" appears

If I manually copy the application from the debug folder to the device and run it from there, it works.

The same deployment error message appears if I try it on an emulator. Other applications are deploying successfully.

Is there any way to make the deployment work? Maybe there is an obscure option I need to set...

What I do is:
Connect the Mobile device to the PC,
Open Visual Studio 2008,
Open a directx sample project,
Click Run (in Debug or Release mode).
