I have an in memory data set in EF Core for .NET 8 along with the method below for saving entities into the context

public static async Task SaveDataToEntitySetAsync<TEntity>(DbContext context, List<TEntity> list) where TEntity : BaseEntity
{
    if (list.Any())
    {
        var dbSet = context.Set<TEntity>();
        var nonNulls = list.Where(x => x != null);

        if(list.Any(x=>x== null))
        {
            throw new Exception($"Null Detected: {list.GetType().Name}");
        }

        foreach (var item in nonNulls)
        {
            dbSet.Add(item);
        
        }

        await context.SaveChangesAsync();
    }
}

This code worked fine in .NET Core 3.1 but in .NET 8 there are no errors but nothing gets saved into the Db context

Has anyone seen this?
