So long, Netduino; may you long live in our hearts.
Netduino is discontinued and has been completely superseded by Meadow.
So long, Netduino. We will remember you in our hearts, and you will long have a place in technology history for setting the gold standard in .NET MicroFramework boards.

You've been good to us, and you've been good to the community. The .NET MicroFramework was a welcome foray into enabling .NET development on embedded devices, and without its inspiration there would be no Meadow.
Big ups to the original .NET MicroFramework team, Colin, Lorenzo, and every one else that built and worked on it. And heart to the entire .NET MicroFramework ecosystem. GHI, Mountaineer, MikroBus, IngenuityMicro, José and the folks at NanoFramework, and all those that played in the sandbox with us; Mark, Craig, Adrian, Frank, Jorge, Scott, others along the way. And of course, the biggest hug to Chris Walker, the original engineer that created Netduino, wherever you may be, amigo.
Wilderness Labs acquired Netduino in 2017 and we used it to help prototype our next gen .NET efforts on embedded as well as support the community that built around it. We fixed old bugs and created Netduino.Foundation (the precursor to Meadow.Foundation) to make it plug and play with sensors, and we had a blast.
However, the technological progress of humankind marches inevitably forward, and from day one, we had a vision of putting the full goodness of the .NET experience on embedded hardware. Meadow realizes that vision, and so that's where our efforts now go.
We look back on you, Netduino, with fondness. And now we look forward.
For those of you with Netduino boards
Netduino is 100% open source:
You can find Netduino documentation at developer.wildernesslabs.co/Netduino/.
If you have legacy NetMF solutions built on Netduino, and are in search of NetMF modules, Ingenuity Micro makes fantastic NetMF SOMs.
