InteractiveMode | Newtonsoft.Json.JsonConvert.SerializeObject | Method has zero rva - f#

Question

Env: OS-X / Xamarin Studio 6.1 / F# Interactive for F# 4.0
Compiled: The following works fine as compiled:
type Movie = {
Name : string
Year: int
}
[<EntryPoint>]
let main argv =
let movies = [
{ Name = "Bad Boys"; Year = 1995 }
]
let json = Newtonsoft.Json.JsonConvert.SerializeObject(movies)
System.Console.WriteLine json
System.Console.ReadKey() |> ignore
0 // return an integer exit code
Interactive: In interactive mode Newtonsoft.Json' JsonConvert.SerializeObject fails
type Movie = {
Name : string
Year: int
}
let movies = [
{ Name = "Bad Boys"; Year = 1995 }
]
let json = Newtonsoft.Json.JsonConvert.SerializeObject(movies)
Output:
val movies : Movie list = [{Name = "Bad Boys";
  Year = 1995;}; {Name = "Bad Boys 2";
  Year = 2003;}]
 System.BadImageFormatException: Method has zero rva

I am missing some setup or does Newtonsoft.Json not work in F#'s Interactive mode.
Note: I am using Xamarin Studio to add all references automatically to the interactive session (152 of them)
Update:
Using Xamarin Studio:
Edit / Send references to F# Interactive:
Which includes:
--> Referenced '/Users/sushi/code/sushi/GeneticGraphDatabase/packages/Newtonsoft.Json.9.0.1/lib/net45/Newtonsoft.Json.dll' (file may be locked by F# Interactive process)
JsonConvert.SerializeObject Produces:
System.BadImageFormatException: Method has zero rva
Referencing it 'manually' with the same assembly path:
#r "/Users/sushi/code/sushi/GeneticGraphDatabase/packages/Newtonsoft.Json.9.0.1/lib/net45/Newtonsoft.Json.dll";;
--> Referenced '/Users/sushi/code/sushi/GeneticGraphDatabase/packages/Newtonsoft.Json.9.0.1/lib/net45/Newtonsoft.Json.dll' (file may be locked by F# Interactive process)
Works as expected:
val json : string = "[{"Name":"Bad Boys","Year":1995}]"

Answer 1

Referencing Json.Net 'manually' using the same assembly path that Xamarin Studio is using when using the menu item: "Edit / Send references to F# Interactive"
#r "/Users/sushi/code/sushi/GeneticGraphDatabase/packages/Newtonsoft.Json.9.0.1/lib/net45/Newtonsoft.Json.dll";;
--> Referenced '/Users/sushi/code/sushi/GeneticGraphDatabase/packages/Newtonsoft.Json.9.0.1/lib/net45/Newtonsoft.Json.dll' (file may be locked by F# Interactive process)
Works as expected:
val json : string = "[{"Name":"Bad Boys","Year":1995}]"
