Hi,

Sharing a basic example using which we can create Parent entity and the related entity records in the same operation\

public MainPage()
 {
 InitializeComponent();
 }

GGContext context;

private void UserControl_Loaded(object sender, RoutedEventArgs e)
 {
 var orgServiceUrl = "http://servername/orgname/XRMServices/2011/OrganizationData.svc";

 // initialize the context
 context = new GGContext(new Uri(orgServiceUrl));

// using client http stack
 context.HttpStack = System.Data.Services.Client.HttpStack.ClientHttp;
 context.UseDefaultCredentials = false;
 context.Credentials = new NetworkCredential("administrator", "password", "domain");
 // create contact record
 Contact contact = new Contact();
 contact.LastName = "Rana";
 contact.FirstName = "Nisha";

 // create two tasks and one email activity
 var myTask1 = new Task();
 myTask1.Subject = "Task1 created at " + DateTime.Now.ToLongTimeString();
 var myTask2 = new Task();
 myTask2.Subject = "Task2 created at " + DateTime.Now.ToLongTimeString();
 var myEmail = new Email();
 myEmail.Subject = "Email created at " + DateTime.Now.ToLongTimeString();

// add the tasks and email to their respective set
 context.AddToTaskSet(myTask1);
 context.AddToTaskSet(myTask2);
 context.AddToEmailSet(myEmail);

// add contact to be created to the contact set
 context.AddToContactSet(contact);

// add the related records
 contact.Contact_Tasks.Add(myTask1);
 contact.Contact_Tasks.Add(myTask2);
 contact.Contact_Emails.Add(myEmail);

 // add the link
 // http://inogic.blogspot.com/2011/12/odata-properties-and-methods-explored.html
 context.AddLink(contact, "Contact_Tasks", myTask1);
 context.AddLink(contact, "Contact_Tasks", myTask2);
 context.AddLink(contact, "Contact_Emails", myEmail);

context.BeginSaveChanges(CreateContactHandler, contact);
 }
 private void CreateContactHandler(IAsyncResult result)
 {
 // in the call back method call the EndSaveChanges method
 // it returns DataServiceResponse object.
 // we can get the error information from this object in case an operation fails
 context.EndSaveChanges(result);
 // id of the created contact record
 Guid createdContactGuid = ((Contact)result.AsyncState).ContactId;
 }

Hope it helps
