Project is using Full .NET 2.0 API, but link.xml is still required to access some of Full features, otherwise Method Not Found() is thrown. With link.xml Null Reference exceptions are being thrown.

STR:

1. Open my attached project.
2. Deploy it on a iOS device, make sure that IL2CPP is selected as scripting backend.
Pay attention to XCode log, NullReferenceException should be thrown:

NullReferenceException: A null value was found where an object instance was required.
at System.Net.AuthenticationManager.DoAuthenticate (System.String challenge, System.Net.WebRequest request, ICredentials credentials) [0x00000] in <filename unknown>:0

This does not happen on Mono2x backend.

Reproduced with: 5.3.5f1, 5.4.2f2, 5.5.0b10
