Windows 10 IoT is an operating system, where .Net-based applications may run on. This has nothing to do with NetMF, on which Netduino is based on. NetMF is a reduced .Net framework while on W10 IoT the full .Net framework is available,
Windows Remote Arduino gives only a possibility to control the Arduino I/O from a Windows application.
So you cannot use W10 IoT on Netduino. Install W10 IoT on a Raspberry and you have a more powerfull MC then Netduino, but both solutions are not comparable, also Netduino has some advantages. In W10 IoT the applications are embedded in the W10 OS, in Netduino the NetMF is the OS, Apps are started emmediatly.
