There have been a few enquiries about the compatibility of the controls and Visual Studio 2008 (especially the
ColorTab Control).
With the developer demo and the purchased controls there is a Visual Studio 2005 and a Visual Studio 2008 install.
The controls in the Visual Studio 2005 install are to be used in Visual Studio 2005 targeting the .NET Compact Framework 2.0
The controls in the Visual Studio 2008 install are to be used in Visual Studio 2008 targeting the .NET Compact Framework 3.5
So, when upgrading your project to Visual Studio 2008, you must right click on the project in the solution using the Pocket PC Controls.com control and upgrade it to target .NET Compact Framework 3.5, then remove the reference to the old Pocket PC Controls.com control (targeting .NET 2.0) and add the control targeting Visual Studio 2008 and targeting .NET Compact Framework 3.5. The projects are not automatically updated to target .NET CF 3.5 when upgrading the solution to Visual Studio 2008
