title: Activation error occured while trying to get instance of type Database, key "" <-- blank
body: <p>I'm trying out the Enterprise Library 5.0 and was doing some unit-tests on my BL, do I need to have a app.config on the DL or on the Test project?</p>
  
  <p>note: I already have the configuration settings on my web.config on my web project.</p>
  
  <p><strong>how I use the DAAB:</strong></p>
  
  <pre><code>private static Database db = DatabaseFactory.CreateDatabase();
  
  db.ExecuteNonQuery("spInsertSalesman", salesman.Fullname);
  </code></pre>
  
  <p><strong>my app.config on DL:</strong></p>
  
  <pre><code>&lt;configuration&gt;
      &lt;configSections&gt;
          &lt;section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" /&gt;
      &lt;/configSections&gt;
      &lt;dataConfiguration defaultDatabase="DBTEST" /&gt;
