c# - Missing method DeserializeObject in assembly.... in MonoDevelop+Newtonsoft -

i have problem when deserializing serialized json c# object using newtonsoft jsonconvert. on linux platform , using monodevelop.

i getting following error message in terminal:

missing method deserializeobject in assembly /home/deepalj/tmp/c#temp/serializertest/serializertest/bin/debug/serializertest.exe, type newtonsoft.json.jsonconvert 

following code deserialization:

using system; using system.web.script.serialization;  using newtonsoft.json;      namespace serializertest     {         class mainclass         {             public static void main (string[] args)             {                 payment p = newtonsoft.json.jsonconvert.deserializeobject<payment> ("{ id: 10, card: 'visa', amount: 1}");                 console.writeline ("card: "+p.card+"\n"+"amount: "+p.amount);             }         }     } 

following payment class:

using system;  namespace serializertest {     public class payment     {         public int id { get; set; }         public string card { get; set; }         public decimal amount { get; set; }     } } 

any fix helpful.

thanks.

i figured out solution. instead of adding newtonsoft.json package references->edit references->packages , included .net assembly manually using references->edit references->.net assembly. downloaded newtonsoft json pakage here , added bin/net45/newtonsoft.json.dll .net assembly. works well.
