I am very pleased to announce TaskVision, our first, major smart client sample application, went live yesterday on our www.windowsforms.net community site!!!!
See http://www.windowsforms.net/taskvision
TaskVision is a task management solution -- which you can use for bug tracking, handling customer service requests, managing a team out in the field, and so on.
Above all, it provides a great source of reusable code and architectural design patterns, demonstrating the power of Windows Forms, no-touch deployment, localization, COM interop, GDI+, asynchronous XML Web services, a model for taking data offline, and more!
You'll note that the TaskVision site on www.windowsforms.net points to a discussion forum focused specifically on TaskVision and managed by the Windows Forms team. If you have questions, that's where to send them. We'll be on the lookout.
In March, we'll be launching Pocket TaskVision - a version of the client built for the .NET Compact Framework. Around that time, we'll also be launching a C# version of the source code.
thanks,
Mike Kass
.NET Framework team
