Windows 10 IoT on Raspberry Pi (or anywhere else) is just 32 bit arm for 
now, so you want to try the armv7-win32-msvc target triplet instead.

(There is some preliminary support for aarch64-win32 targets also; it 
seems to work for C code for things I've tested so far, but e.g. C++ 
support is incomplete. And there's no public aarch64 windows version out 
at all yet, it's supposedly coming late this year though. So far I've been 
testing it with wine.)
