N:1 relationships between custom entities
Could we get an example (in c#preferrably) of retrieving a list of custom entities that have a N:1 relationship to another custom entity.  The criteria would only be the parent entity guid.
We know the metadata name of the custom entity, therefore it does not need to use DynamicEntities.
I have tried a RetrieveMultipleRequest using a QueryExpression with one LinkEntity defined but am getting "Server was unable to process request" errors.
Tried to follow the example of N:N from http://blogs.javista.com/2008/02/17/crm-40-relationships-explained-many-to-many/

also in the catch  before main exception

// your code
catch (System.Web.Services.Protocols.SoapException ex)
                string errorMessage = ex.Message.ToString();
                //Handle the error
catch (Exception ex1)
                //Handle the error
