After exporting the attached project to iOS/IL2CPP using .NET Standard 2.0, XCode fails to compile.

Steps:
1. Open the attached project ("Microsoft.ProjectOxford.Face.zip") with 2018.1 and set Build target to iOS
2. Build Settings > Api Compatibility Level: .NET Standard 2.0
3. Build and run using Xcode

Result: Xcode fails to compile project due to errors:
/Users/lukasa/Desktop/Microsoft.ProjectOxford.Face/aaa/Classes/Native/Bulk_System_1.cpp:22906:81: No member named 'GetHostByName40' in 'il2cpp::icalls::System::System::Net::Dns'; did you mean 'GetHostByName'?
/Users/lukasa/Desktop/Microsoft.ProjectOxford.Face/aaa/Classes/Native/Bulk_System_1.cpp:22913:81: No member named 'GetHostByAddr40' in 'il2cpp::icalls::System::System::Net::Dns'; did you mean 'GetHostByAddr'?

Reproduced with: 2018.1.0b5.
Not reproduced with: 2017.3.1f1 (due to Errors in the Unity Console).

Tested with: iPad Pro 12.9 (2017) iS 11.2.1, Xcode 9.2.

Note: no error in Xcode when Api Compatibility Level is set to .NET 4.6.
