title: Hierarchyid data type and Code First
body: <p>What I need to do, I have a comment table using the HierarchyID data type in sql server, and would like that mapped over to a Code First/EF 4.3 class. How can I achieve this?</p>
  
  <p>Also how do I interact with the hierarchyID when inserting/deleting. Thank you very much.</p>
