Note:
.NET Core use the Core version, and other platforms use the Framework version or Standard version.
Because the Core version is performance-optimized.
the Framework version and Standard version are optimized for compatibility.
the Framework version and Standard version can run directly on AOT platforms.
注意：
.NET Core 请使用 Core 版本，其他平台和运行时请使用 Framework 版本或 Standard 版本。
因为 Core 版本专为性能优化，Framework 版本和 Standard 版本为兼容性优化。
Framework 版本和 Standard 版本可以直接在 AOT 平台上运行。
LoopReferencingNull:
Objects that appear a loop reference during serialization are treated as Null.
在序列化时出现循环引用的对象将用 Null 表示。
MultiReferencingReference:
Allow use { "$ref": "#/obj/1/target" } to represent objects that are repeatedly referenced.
允许使用 { "$ref": "#/obj/1/target" } 写法表示重复引用的对象。
AsOrderedObjectDeserialize
Perform as-ordered object fields parsing, which can improve parsing performance of ordered msgpack objects.
执行假定有序的对象字段解析，这可以提高有序 msgpack 对象的解析性能。
CamelCaseWhenSerialize
Convert the fields name in the object to camel case during serialization.
序列化时，将对象中的字段名称转换为骆驼命名法。 ::: new { Name = "Dogwei" } -> { "name": "Dogwei" }
IgnoreNull | IgnoreZero | IgnoreEmptyString
Null, 0, "" values are ignored during serialization.
序列化时分别跳过 Null, 0 和 "" 值。 ::: { A = (string)null, B = 0, C = "", D = 1 } -> { "D": 1 }
