[Ironruby-core] Bug in mscorlib, IronRuby, NewtonSoft.json..... or my code?

[Ben Hall]

Hi,

I'm trying to use a third party library which has a dependency on
NewtonSoft.json. I create a class within IronRuby and attempt to
serialise the object to Json however it throws a null reference
exception from within mscorlib.

Any ideas?? Example is below:

Thanks

Ben

class Company
  attr_accessor :Name, :Id
end

c = Company.new
c.Name = 'test'


require 'Newtonsoft.Json'
include Newtonsoft::Json
JsonConvert.serialize_object c
