I've been away from Netduino as well. I've got a regular netduino no plus or anything. What software do I need to get and in what order. C# express 2010 is no longer an option. I'm pretty new and need pretty clear instructions or I'm sure I'll mess something up.
Visual Studio 2013 Express and the NETMF 4.3 SDK should work for you; just be sure to change the target framework to the earlier version of .NETMF running on your device.
Head over to the Downloads page. Install VS2013 Express, the NETMF SDK, the NETMF plug-in for VS2013, and then the Netduino SDK. And then...install the legacy templates (for Netduino 1). [Yes, I know that's a lot of installs...sorry about that.]
