Good to see you! Hope you can stick around a bit to fiddle with things...
There is no longer a production of a Visual Studio XML project file. Instead it produces an "nmake" form makefile.
I'd been doing target: nmake and then the build steps are:
nmake prep
nmake folders
nmake
But I should have made that the default for the Visual studio configs. Now I have done so, so you won't need the target: nmake:
