Method not found: Newtonsoft Json exception at runtime c# MVC application

Hi ,

I am getting at runtime 'Void Newtonsoft.Json.Serialization.DefaultContractResolver.set_IgnoreSerializableAttribute(Boolean) exception when i run an MVC 4 application, whereas the same code (shared via TFS) is running perfectly in another system.
Both the system have Target framework 4.5 and Newtonsoft Json version 4.5 and Microsoft.AspNet.WebApi.Client.4.0.30506.0 package
(I am getting the exception at WebApiConfig.Register(GlobalConfiguration.Configuration); line.)

Can i know how to resolve it ? It urgent !

Hi,

You need to install the NewtonSoft.Json from the Nuget package in the project.

Hi,

If you have any older version in GAC also throws you this problem.
