title: I do not understand how EF5 dbContext.Entry(entity).Reload() method is supposed to work?
body: <p>In this example :</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using dbModel;
  using System.Linq;
  using System.Data.Entity.Infrastructure;
  
  
  namespace WinApp
  {
      public partial class Form1 : Form
      {
          private dbEntities dbc;
          public IQueryable&lt;ARTIKLI&gt; art;
          public IQueryable&lt;ART_GRUPE&gt; grp;
  
          public Form1()
          {
              InitializeComponent();
              dbc = new dbEntities();            
          }
  
  
          private void GetData()
          {
              art = from a in dbc.ARTIKLIs
                          select a;
  
              grp = from g in dbc.ART_GRUPE
                          select g;
  
              artikliBindingSource.DataSource = art.ToList();
              artGrupeBindingSource.DataSource = grp.ToList();
          }
  
  
          private void Form1_FormClosing(object sender, System.Windows.Forms.FormClosingEventArgs e)
          {
              dbc.SaveChanges();
          }
  
  
          private void loadData_Click(object sender, EventArgs e)
          {
              this.GetData();  
          }
  
  
          private void refresh_Click(object sender, EventArgs e)
          {
  
              dbc.Entry(grp).Reload();
              artGrupeBindingSource.ResetBindings(false);
          }
  
      }
  }
  </code></pre>
  
  <p>everything builds OK. But when I run and click Refresh button I get error :</p>
  
  <blockquote>
    <p>The entity type DbQuery`1 is not part of the model for the current context</p>
  </blockquote>
  
  <p>I am just trying to refresh data from store for <code>grp</code> entity instance using <code>DbContext</code>. I know I can convert <code>DbContext</code> into <code>ObjectContext</code> and then use <code>Refresh</code> method, but
  it should be possible to do the same with <code>DbContext.Entry(entity).Reload();</code></p>
  
  <p>Can someone explain my mistakes in the code above? </p>
