using doob.Reflectensions.Json;
var json = Json.Converter.ToJson(obj);
var obj = Json.Converter.ToObject<T>(json);

var json = JsonSerializer.Serialize(obj);
var obj = JsonSerializer.Deserialize<T>(json);

Type Name Strings

// Before
TypeHelper.FindType("doob.Reflectensions.Tests.MyClass")

// After
TypeHelper.FindType("Cocoar.Reflectensions.Tests.MyClass")

Target Framework Changes

Before	After
.NET 7.0	.NET 8.0

If you were targeting .NET Framework 4.7.2 directly, you can still use Reflectensions through .NET Standard 2.0 compatibility (.NET Framework 4.6.1+).
