title: EF Effort Testing Library Throws 'TargetInvocationException'
body: <p>When trying to create an ObjectContext using the CreateTransient factory with a loader, I'm consistently getting an error: </p>
  
  <blockquote>
    <p>"TargetInvocationException was unhandled by user code"</p>
  </blockquote>
  
  <p>with an inner exception of:</p>
  
  <blockquote>
    <p>"The specified named connection is either not found in the
    configuration, not intended to be used with the EntityClient provider,
    or not valid"</p>
  </blockquote>
  
  <pre><code>var loader = new CsvDataLoader(@"C:\MyProject\MyProject.Tests\Data\Info.csv");
  
  using (var context = ObjectContextFactory.CreateTransient&lt;MyEntities&gt;(loader))
  {
      ...
  }
  </code></pre>
  
  <p>I can create a standard context just fine, and I can create a Transient ObjectContext without a loader, but I can not load a csv file. The csv was generated by the Effort export tool.</p>
