Cannot serialize/deserialize object without parameterless constructor

[mongeon]

I've started using the HierarchyId for a Blazor project I've started and it's was failing as it's use Json for serialize/deserialize object and HierarchyId doesn't have one. I've create a simple converter to perform the task. I'm not sure if this should belong in this repository or not.

using Microsoft.EntityFrameworkCore;
using System;
using System.Text.Json;
using System.Text.Json.Serialization;

namespace ANamespace
{
    public class HierarchyIdConverter : JsonConverter<HierarchyId>
    {
        public override HierarchyId Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
        {
            return HierarchyId.Parse(reader.GetString());
        }

        public override void Write(Utf8JsonWriter writer, HierarchyId value, JsonSerializerOptions options)
        {
            writer.WriteStringValue(value.ToString());
        }
    }
}

Are there any BCL annotations we can add to HierarchyId to make it more JSON-friendly?

If anyone would still like to see out-of-the-box support for serializing to JSON, please submit an issue on dotnet/efcore.

We decided to add a built-in JSON converter to EF8
