Entity Framework and Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

I had troubles with long list in "delete" action. After several unsuccessful attempts I found solution (maybe is not the best):

using (var ctx = new EntityContext())

{

  var tmpTimeout = ctx.CommandTimeout;

  try

  {

   ctx.CommandTimeout = int.MaxValue;

   ctx.YOUROBJECTS.DeleteObject(value));

   ctx.SaveChanges();

  }

  catch (Exception ex)

  {}

  finally

  {

   ctx.CommandTimeout = tmpTimeout;

  }

}
