How to map Shadow Properties in AutoMapper

I'm using shadow properties to inject specific properties into many entities by iterating on them in OnModelCreating method.

protected override void OnModelCreating(ModelBuilder builder)
{
    foreach (var entityType in builder.Model.GetEntityTypes())
    {
        // Configure LastModified, ModifiedBy on all entities
        builder.Entity(entityType.Name).Property<DateTimeOffset>("LastModified").HasDefaultValueSql("now()");
        builder.Entity(entityType.Name).Property<string>("ModifiedBy");

        // Configure IsActive on entities with SoftDelete Attribute
        if (Attribute.IsDefined(entityType.ClrType, typeof(SoftDeleteAttribute)))
        {
            builder.Entity(entityType.Name).Property<bool?>("IsActive").HasDefaultValue(true);
        }
    }
}

I'm using AutoMapper to map my entities to DTOs / Models. The problem is it cannot see this dynamically created property in my Entity Class.

I tried MapAtRuntime() method, and tried using the following:

.ForMember(m => m.IsActive, m => m.MapFrom("IsActive"))

However it either doesn't map in the first case, or in the second case would throw an exception that the property is not found on the class.

I tried the solution in the following issue, but it didn't work either! enter link description here

Gives an "Error mapping types." Exception.

Any thoughts would be appreciated.
