title: LINQ statement is returning "Invalid object name" error
body: <p>I'm completely new to LINQ. I'm just trying to do some easy stuff but I got an error:     </p>
  
  <blockquote>
    <p>Invalid object name 'dbo.grupyTowarowe'.</p>
  </blockquote>
  
  <p>I could have sworn this worked couple min ago and I didn't change anything.</p>
  
  <p>This is the code:</p>
  
  <pre><code>var papier = from GrupyTowarowe in dbContext.grupyTowarowes
               where GrupyTowarowe.typ == "moneta"
               select new
               {
                   GrupyTowarowe.grupa
               };
  
  dataGridView1.DataSource = papier;
  </code></pre>
  
  <p>The error is shown on the DataGridView.</p>
