title: Updating multiple rows at once with Entity Framework
body: <p>I am trying to figure out if there is a way to update multiple rows at once with Entity.</p>
  
  <p>For now I am using Linq2Sql SubmitChanges which will perform an update row by row: </p>
  
  <pre><code>c.PROPERTYONE = valueOne;
  c.PROPERTYTWO = valueTwo;
  ...
  dataContext.SubmitChanges();
  </code></pre>
  
  <p>In my case, valueOne and valueTwo will most likely change for each iteration.</p>
  
  <p>I would like to know if it's possible to store for example, up to 1000 rows and update them at once.</p>
  
  <p>I know how to do it with inserts (by getting the DbContext instance, the appropriate table, calling the Add function then SaveChanges) but I'm struggling in finding the equivalent for updates.  </p>
  
  <p>Thanks in advance!</p>
