Type of issue

Missing information

Description

Based on my understanding, FrozenDictionary<TKey,TValue> is a type designed to be immutable and read-only. I would have expected this type to be thread safe. I have checked the official documentation of the type, but I have found no mention about its thread safety.

Based on my experience, thread safety of dotnet types is documented explicitly. For instance, the thread safety of ImmutableDictionary<TKey,TValue> is explicitly documented here. Given the lack of explicit documentation for FrozenDictionary<TKey,TValue>, I must assume it as not being thread safe, even if that seems counter-intuitive given the described characteristics of that type.

Can you please clarify this point in the documentation, or point me to the correct resource if any ?

Many thanks.
