Domain service extension method

This little extension method is something I wrote to help cleanup domain context code… just thought I would share:

public static class DomainContextExtensions
{
  public static void Load(this DomainContext domainContext,
                          EntityQuery query,
                          Action<LoadOperation> preprocessCallback,
                          Action<LoadOperation> successCallback,
                          Action<LoadOperation> errorCallback,
                          Action<LoadOperation> postprocessCallback = null)
    where TEntity : Entity
  {
    domainContext.Load(query, load =>
    {
      if (preprocessCallback != null)
        preprocessCallback(load);

      if (load.HasError)
      {
        if (errorCallback != null)
        {
          errorCallback(load);
          load.MarkErrorAsHandled();
        }
      }
      else
      {
        successCallback(load);
      }

      if (postprocessCallback != null)
        postprocessCallback(load);
    }, null);
  }
}

Enjoy!
