Change MaxValueLenght for NewValue and OriginalValue properties in EntityPropertyChange

Hi, i have problem with NewValue and OriginalValue related with this closed issue: https://github.com/aspnetboilerplate/aspnetboilerplate/issues/4203

like as @mwj033 mentioned in above issue, OnModelCreating did not any effect. @ryancyq sugestion is not enough to solve this problem. Yes, in database NewValue column was changed to character varying (1024 * 6), but when repository insert property change ORM entity, NewValue is truncated to 512 chars. I was tried to replace DbSet using new keyword and change EntityHistory objects

        public new DbSet<TopEntityChange> EntityChanges { get; set; }
        public new DbSet<TopEntityPropertyChange> EntityPropertyChanges { get; set; }

where NewValue and OriginalValue are overrided

    [Table("AbpEntityPropertyChanges")]
    public class TopEntityPropertyChange: EntityPropertyChange
    {
        public override string NewValue { get; set; }
        public override string OriginalValue { get; set; }

        public new const int MaxValueLength = 1024 * 6;
    }

but did not help. Have you any idea how to increase number of chars for NewValue and OriginalValue ?

Yes! Correct!

Remaining steps:

1. Import Nuget Abp.ZeroCore.EntityFrameworkCore
2. Copy https://github.com/aspnetboilerplate/aspnetboilerplate/blob/dev/src/Abp.ZeroCore.EntityFrameworkCore/EntityHistory/EntityHistoryHelper.cs
3. Copy https://github.com/aspnetboilerplate/aspnetboilerplate/blob/0fcb1bc10dd8d78e0e2b5fd87ca14c897b399c77/src/Abp.ZeroCore.EntityFrameworkCore/EntityHistory/Extensions/EntityEntryExtensions.cs#L15
4. Copy https://github.com/aspnetboilerplate/aspnetboilerplate/blob/0fcb1bc10dd8d78e0e2b5fd87ca14c897b399c77/src/Abp.ZeroCore.EntityFrameworkCore/EntityHistory/Extensions/PropertyEntryExtensions.cs#L8
5. Change your EntityHistoryHelper and its method CreateEntityPropertyChange. Apply a new extended model instead of EntityPropertyChange (I changed to FullEntityPropertyChange).
6. Don’t forget about: Configuration.ReplaceService<IEntityHistoryHelper, MyEntityHistoryHelper>(DependencyLifeStyle.Transient);

Thanks @ismcagdas it works 👍
