What is "unclear" to me is that I have each .lib listed in the .mke file as a linker "Dependency". It's only when I additionally listed "mfcs120u.lib" and "msvcrt.lib" as Dependencies did the code link. Up until this point, I have never had a need to include those two files as "Additional Dependencies" - the linker was happy (until I tried to use those two TextBlock functions)....
