Question

环境：OS-X / Xamarin Studio 6.1 / F＃Interactive＃F <4.0

已编译：以下版本可以正常编译：

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

互动：在交互模式下Newtonsoft.Json＆＃39; JsonConvert.SerializeObject失败

type Movie = {
    Name : string
    Year: int
}
let movies = [
    { Name = "Bad Boys"; Year = 1995 }
]
let json = Newtonsoft.Json.JsonConvert.SerializeObject(movies)

输出：

val movies : Movie list = [{Name = "Bad Boys";
                             Year = 1995;}; {Name = "Bad Boys 2";
                                             Year = 2003;}]

我缺少一些设置或者Newtonsoft.Json无法在F＃的交互模式下工作。

注意：我正在使用Xamarin Studio自动将所有引用添加到交互式会话中（其中152个）

更新

使用Xamarin Studio：

编辑/发送对F＃Interactive的引用：

其中包括：

--> 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产生：

System.BadImageFormatException: Method has zero rva

手动参考＆＃39;使用相同的装配路径：

#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)

按预期工作：

val json : string = "[{"Name":"Bad Boys","Year":1995}]"

Answer 1

使用Xamarin Studio在使用菜单项时使用的相同程序集路径，手动引用wstart ＆＃39; ：Json.Net

"Edit / Send references to F# Interactive"

按预期工作：

#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)

InteractiveMode | Newtonsoft.Json.JsonConvert.SerializeObject |方法有零rva
