Cross Platform Primitive Types with Generics

Source/destination types

public class TestClass<T>
{
    public int A { get; set; }
    public T B { get; set; }
}

Source/destination JSON

With UWP/.NetCore:

{
    "$type": "AppTest.MainPage+TestClass`1[[System.Int32, System.Private.CoreLib]], AppTest",
    "A": 1,
    "B": 2
}

With .NET Framework

{
    "$type": "AppTest.MainPage+TestClass`1[[System.Int32, mscorlib]], AppTest",
    "A": 1,
    "B": 2
}

Expected behavior

Successful deserialization. Or the suggested fix of serializing primitives without the assembly name:

{
    "$type": "AppTest.MainPage+TestClass`1[[System.Int32]], AppTest",
    "A": 1,
    "B": 2
}

Actual behavior

Runtime Exception:

Newtonsoft.Json.JsonSerializationException: ‘Error resolving type specified in JSON ‘ConsoleApp3.Program+TestClass`1[[System.Int32, mscorlib]], ConsoleApp3’. Path ‘$type’, line 1, position 81.’

Steps to reproduce

1. Serialize class with TypeNameHandling (Tested with TypeNameHandling.Objects)

 string serialized = JsonConvert.SerializeObject(a, new JsonSerializerSettings() { TypeNameHandling = TypeNameHandling.Objects});

1. Deserialize json file on a different .Net system a. That is, .NETFramework if UWP/.NETCore, and vice versa.

object deserialized = JsonConvert.DeserializeObject(serialized, new JsonSerializerSettings() { TypeNameHandling = TypeNameHandling.Objects });

@danebou i didnt consider my suggestion a “fix”, just a workaround. My preference would be that this scenario was supported OOTB

[SimonCropp]

potential workaround?

    AppDomain.CurrentDomain.AssemblyResolve += (sender, args) =>
    {
        if (args.Name == "System.Private.CoreLib")
        {
            return typeof(int).Assembly;
        }

        return null;
    };
