runtime: PlatformNotSupportedException when attempting to serialize DirectoryInfo instance with Newtonsoft.Json

Cross-posting with https://github.com/JamesNK/Newtonsoft.Json/issues/1404 to demonstrate the pain this can cause with 3rd party libraries that have historically relied on this behavior vs simply removing the API which would bring attention to the problem immediately, instead of at runtime.

Please consider removing these APIs in the future

Source/destination types

System.IO.DirectoryInfo

Source/destination JSON

None/serialization fails.

Expected behavior

Serialization of the DirectoryInfo object to function how it works on .net 4.x

Actual behavior

Message: System.PlatformNotSupportedException : Operation is not supported on this platform.

Appears to be related to a change made in the .net core implementation to no longer support serializing several types. https://github.com/dotnet/corefx/pull/20220

var di = Directory.CreateDirectory("C:\\this\\doesnt\\exist");
var json = JsonConvert.SerializeObject(di);
Console.WriteLine(json);

Other Observations

SerializerSettings.Error = (s, e) => e.ErrorContext.Handled = true; does not handle this exception setting SerializerSettings.ContractResolver = new DefaultContractResolver { IgnoreSerializableInterface = true }; does not change this behavior
