title: Entity Framework 4 SaveChanges Method not saving to database
body: <p>I'm trying to use Entity Framework 4 for a small database application I'm writing to keep record of downloaded files. When running the application I set a break point after the tableName.Add() method, before the .SaveChanges() method and I can see the data saved into the entity; then I have another break point after calling the .SaveChanges() method, and look into the database to find there is no record saved to it. I have found a lot of similar questions, but I have not found the solution to my particular problem. Here is the code:</p>
  
  <pre><code>    public void StartNewDownload(string FileID)
      {
          DateTime startTime = DateTime.Now;
  
          FilesDBEntities db = new FilesDBEntities();
          int startedID = (from dr in db.tblDownloadResults
                           where dr.Value.Equals("Started")
                           select dr.ResultID).First();
          tblDownloads myDownload = new tblDownloads { FileID = FileID, StartDateTime = startTime, ResultID = startedID };
          db.tblDownloads.Add(myDownload);
          db.SaveChanges();
      }
  </code></pre>
  
  <p>Any help is appreciated.</p>
  
  <p>Thanks!</p>
