Microsoft have recently totally re-vamped the .NETMF website. In a major and long over due refresh Microsoft have hinted that the IoT (Internet of Things) will be a big part of the overall eco system approach. Add to that the recent comments by Mr. Nadella about the world of Windows 10 and how it will be a platform spanning many devices, then put two and two together, sprinkle with developer dust and you may come up with a good idea of the future.
Whatever their plans actually are, its clear Microsoft are starting to shape something that includes more focus on integrating micro controllers and small devices, wearables and other tech. This can only be a good thing.
Have a gander at the new site www.netmf.com its well worth it. There a a number of new posts about new hardware that the community have been cooking up. If you have a project why not share it with Microsoft? I am sure they would love to hear about anything you want to share with them.
