Thread safety of ISerializer/IDeserializer

[filzrev]

I want to know ISerializer/IDeserializer is thread-safe or not thread-safe.

On this StackOverflow question.
Project author answered it's safe to be called by multiple threads.

But it can be found some comments that it's not thread safe.

• Singletons, Extensions and Naming Conventions helpers #799
• SerializerBuilder interface for IoC #517 (comment)

Is there any official documents about multi thread behavior?

No, they are not thread safe. You will need to create new serializers and deserializers in each thread.

Thanks for your clarification.

Since serializer/deserializer API is not thread-safe. (SerializerBuilder/DeserializerBuilder also?)
I'll try to create serializer/deserializer per-thread and cache instance by using ThreadLocal functionality.

    private static readonly ThreadLocal<ISerializer> Serializer = new(() =>
      new SerializerBuilder()
      .WithNamingConvention(CamelCaseNamingConvention.Instance)
      .Build()
    );
