I've got a call to a webAPI service using Newton.Json:
response = await client.PostAsJsonAsync(method, data);
but when I make the call I get an IO error looking for version 6 of Newton.Json (I'm on version 5.0.4). The only other package reference I've got in my project are Microsoft.AspNet.WebApi.Client version 5.0.0 - which has a dependency for Newson.Json of at least version 4.5.
Any ideas why this could be happening? I'm using Visual Studio 2013 with IIS.
