I think there is actually a minority which uses the Gadgeteer extension to NETMF. :whistle:
Without having the Gageteer core released for 4.3.1 (QFE1) it’s useless for them.
The problem is around versioning, as 4.3 QFE1 is actually 4.3.1, its a small thing but actually significant in terms of what version of 4.3 you can use in the firmware, but to be expected considering how long 4.3 has been out there already. So some of the work done getting to 4.3 will need to be checked against 4.3.1, but its not a big thing.
