For some reason, all of the project files reference the Windows 8.1 SDK, except for CoreLib, which references a version of the Windows 10 SDK.
At least on my machine, this caused the build to fail (possibly because I didn't have the appropriate version of the SDK installed?), while switching to consistently use the 8.1 SDK on all projects led to a successful build.
