using (AdventureWorksEntities context =

{
Contact contact = new Contact();
// Create a new SalesOrderHeader.
SalesOrderHeader newSalesOrder1 = new SalesOrderHeader();
// Add SalesOrderHeader to the Contact.
contact.SalesOrderHeaders.Add(newSalesOrder1);
// Create another SalesOrderHeader.
SalesOrderHeader newSalesOrder2 = new SalesOrderHeader();
// Add SalesOrderHeader to the Contact.
contact.SalesOrderHeaders.Add(newSalesOrder2);
// Get all related ends
IEnumerable<IRelatedEnd> relEnds =
((IEntityWithRelationships)contact).RelationshipManager
.GetAllRelatedEnds();
foreach (IRelatedEnd relEnd in relEnds)
{
Console.WriteLine("Relationship Name: {0}", relEnd.RelationshipName);
Console.WriteLine("Source Role Name: {0}", relEnd.SourceRoleName);
