{
if (uiTestControl == null) throw new ArgumentNullException(“uiTestControl”);
if (id == null) throw new ArgumentNullException(“id”);

SilverlightHyperlink silverLightHyperLink = new SilverlightHyperlink(uiTestControl);
silverLightHyperLink.SearchProperties.Add(new PropertyExpression(SilverlightHyperlink.PropertyNames.AutomationId, id, PropertyExpressionOperator.EqualTo));

return silverLightHyperLink;
