@PsychoBoy11 which "current implementation of JSON" are you referring to?

EF CORE 7.0.0

Having property like:

public class TestEntity
{
     ...
     public List<string> MyProperty;
}

and setting in OnModelCreating:

modelBuilder.Entity<TestEntity>().OwnsMany(t => t.MyProperty).ToJson();

First of all it fails when trying to create migration:
No suitable constructor was found for entity type 'string'. The following constructors had parameters that could not be bound to properties of the entity type: Cannot bind 'value' in 'string(char[] value)' Cannot bind 'value', 'startIndex', 'length' in 'string(char[] value, int startIndex, int length)' Cannot bind 'value' in 'string(Char* value)' Cannot bind 'value', 'startIndex', 'length' in 'string(Char* value, int startIndex, int length)' Cannot bind 'value' in 'string(SByte* value)' Cannot bind 'value', 'startIndex', 'length' in 'string(SByte* value, int startIndex, int length)' Cannot bind 'value', 'startIndex', 'length', 'enc' in 'string(SByte* value, int startIndex, int length, Encoding enc)' Cannot bind 'c', 'count' in 'string(char c, int count)' Cannot bind 'value' in 'string(ReadOnlySpan<char> value)' Note that only mapped properties can be bound to constructor parameters. Navigations to related entities, including references to owned types, cannot be bound.

Second, according to 7.0.0 implementation List gets mapped to comma-separated text field, if that's true, what happens if any of the strings contain comma?

Toolset version: Entity Framework Core .NET Command-line Tools 7.0.0
Coming to think now, string is not a primitive type, so what I am doing wrong?
Thanks for your help.

Json: add support for collection of primitive types inside JSON columns #28688
