Description

Not quite sure what's going on. One time I've got "string" as type. It was working previously, because benchmarks for JSON project has int[] and short[] deserialization test.

Also, based on nanoFramework.Json.JsonConvert.PopulateObject typeof(int[]).GetElementType() should return "int[]" type.

How to reproduce

var type = typeof(short[]);
Console.WriteLine(type.ToString());
Console.WriteLine(type.Name);
Console.WriteLine(type.GetElementType().FullName);

Expected behaviour

Most likely related with a recent fix for array's type...
This means that mscorlib Unit Tests are missing tests for these, otherwise it would have been caught there.

And to help a bit, this is actually working:

ushort[] array = new ushort[10];

  var type = array.GetType();
  Console.WriteLine(type.ToString());
  Console.WriteLine(type.Name);
  Console.WriteLine(type.GetElementType().FullName);

That does return properly:

System.UInt16[]
UInt16[]
System.UInt16

so issue seems to be with typeof for the array system types.

And this crashes directly: var type = typeof(System.UInt16[]);
