Property Value


A JsonSerializerOptions instance can be locked if it has been passed to one of the JsonSerializer methods, has been associated with a JsonSerializerContext instance, or a user explicitly called the MakeReadOnly() methods on the instance.

Read-only instances use caching when querying JsonConverter and JsonTypeInfo metadata.
