Arduino for Visual Studio 2010 has been extended to support Visual Studio 2008. The same functionality and configuration exists between the two versions. The 2010 addin runs .NET4 and the 2008 addin runs .NET3.5, both are installed using a single msi and both share the same configuration settings.
The 2008 installation (msi) has yet to be tested on machines that do not have .NET4 installed. The only known issue in 2008 is that the button and menu icons are missing. Please logon to the visual micro forum and let us know if things are working or not.
