foreach (var task in project.SelectAllChildTasks())
{
    Console.WriteLine("Task:");
    foreach (var propInfo in typeof(Task).GetProperties().Where(propInfo => propInfo.GetCustomAttribute{Attributes.EntityFieldAttribute}() != null))
    {
        Console.WriteLine(string.Format("{0}: {1}", propInfo.Name, propInfo.GetValue(task)));
    }
}
```
