Gadgeteer support for .NET Micro Framework 4.2 is on the way, which means you'll soon be able to run Gadgeteer on .NETMF 4.2-compatible mainboards like GHI's Fez Cerberus. This update also enables Gadgeteer apps to be written using Visual Basic (Visual Studio or Visual Basic 2010 Express).
A beta version of GadgeteerCore is now available on Codeplex for people who want an early peek. Most Gadgeteer modules and mainboards still target NETMF 4.1 so most users won't see anything changed - your existing projects will continue to work as they currently do and you can still create new .NETMF 4.1 compatible projects. If you have a Cerberus and you're feeling adventurous, though, you can try creating a Gadgeteer NETMF 4.2 project. One warning: mainboards and modules won't show up in the designer for NETMF 4.2 apps until their drivers are updated, so you'll need to add references to module assemblies and instantiate them in code.
If you're building Gadgeteer-compatible hardware, you'll need to update your mainboard or module driver to provide NETMF 4.2-compatible assemblies. The changes are minor and are detailed in updated versions of the Mainboard and Module Builder's Guides.

** Quick Update: Visual Basic 2010 Express support didn't make it into this beta, but it will be included in the next one.
