Application passes WACK but does not complete submission certification

Question

I observe a strange situation when my application passes WACK on my computer, but the submission to the store does not pass at the certification stage due to unsupported APIs. I am using MSVC 15 Update 2.

Solution Consists of:

• Universal APP
• Class Library (Universal Windows)
• Class Library (Portable)
• EF Core RC2
• Syncfusion SfChart.UWP.dll

Store certificate output:

Error Detected: The following errors were detected in a supported API:

• The sysctl API in libc.dll is not supported for this type of application. Microsoft.Extensions.PlatformAbstractions.dll calls this API.
• The uname API in libc.dll is not supported for this type of application. Microsoft.Extensions.PlatformAbstractions.dll calls this API.
• API RtlGetVersion ntdll.dll . Microsoft.Extensions.PlatformAbstractions.dll API.
