Storage Side Effect with Database Generated Fields Population

[b564518128]

Hi, I am new to Wolverine and very interested in the side effect concept. I am using EF core with PostgreSql in my project and trying to implement my entity creation handler with side effects.
Suppose I have an entity defined as such

public class Entity {
    int Id {get; set;}   // set by database
    string EntityName {get; set;}
}

When using traditional way for inserting the entity into the database, the Id field can be immediately after calling add before committing to the database.

public static int Handle(Entity entity, EntityDbContext dbContext) {
   dbContext.Add(entity);
   return entity.Id;      // Id is populated when Hilo is enabled right after calling dbContext.Add
}

When using Side Effect, the Id field won't be available inside the main handler

public static (Insert<Entity>, int) Handle(Entity entity, EntityDbContext dbContext) {
   return (Storage.Insert(entity), entity.Id);      // Id will not be populated inside the handler
}

Is there a way to bridge the gap?
