This is a very cool (and looks like fun) example of game programming for the Compact .NET Framework.
Pocket 1945 - A C# .NET CF Shooter
Pocket 1945 is a classic shooter inspired by the classic 1942 game. The game is written in C# targeting the .NET Compact Framework
...
In order to play you need a Pocket PC enabled device with the .NET Compact Framework 1.1 installed. To install simply copy the Pocket1945.exe file and the level XML files to a new folder on your device. No installation is required.
To play the game, you use the direction keys on your device. To exit, click the calendar button (first hardware button). To fire, click the second hardware button. Since I don’t own a real device I’m not sure what the “name” of these buttons are. But, just give it a go!
The current game is far from “finished”, but it is safe to run the code and it is playable. The game consists of 4 levels. To add levels of your own, simply make new level XML files and copy them to the game folder on your device.

Get FlexWallet 2005 (with FREE Desktop Edition) by Two Peaks Software from Handango
Two Peaks has released a major upgrade for their FlexWallet program, and it's nice! Upgrading was easy--you can just import your old wallet. They have all new icons--XP style, and more of them. Other new features include the ability to edit templates even though there are cards using the templates, unlimited fields in each template, support for landscape and hi-res VGA devices, faster encryption, text or numeric lock codes, the list goes on. I'm digging it. Also, a minor update is promised that we can use custom icons as well.
Another cool Smart Client Code Sample
FotoVision
The FotoVision sample allows you to easily share photos on the web and demonstrates a variety of .NET technologies including Windows Forms, ASP.NET, Web services, and the .NET Compact Framework. It consists of a desktop, web, and Pocket PC sample applications. This paper provides information so you can get the most from the FotoVision desktop application.

I thought that the FotoVision page at MS would have been fixed by the time this got posted. Guess not, and it's still not correct. In addition to Frank's blog entry that Colt points out below, Jonathon Wells also has the correct links for the various pieces.
