title: getting the ID of newly added recorded using linq to entities
body: <p>Hi this is my first project using linq to entities. I've figured out how to create a new record I just need to get the ID that was assigned to it so I can use it as a FK in an extension table when I add the entries there. I'm allowing users to create request, the request can be for multiple pieces of equipment so I have a Request and RequestedEquipment table. Here is the code I'm using to create the request:</p>
  
  <pre><code>public void addReq(ReqType reqType, Employee reqBy, Location loc, string comm)
          {
              int reqID;
              Request req = new Request();
              req.Comments = comm;
              req.Employee = reqBy;
              req.ReqType = reqType;
                  req.RequestStatus = findReqStat(1);
              req.Location = loc;
              entities.AddToRequests(req);
              entities.SaveChanges();
          }
  </code></pre>
  
  <p>How can I get the ID of the request that was created so I can use it to Create the needed entries in the RequestedEquipment Table?</p>
