title: How to have multiple projects accessing same Entity Framework project?
body: <p>Ok, this question has been asked many times.  Just googling with the error message:</p>
  
  <pre><code>The specified named connection is either not found in the configuration,
  not intended to be used with the EntityClient provider, or not valid.
  </code></pre>
  
  <p>I have tried all suggestions on forums, help sites et blogs... nothing works!</p>
  
  <p><strong>Situation recap</strong></p>
  
  <p>I'm splitting solution into three different projects: one for my model with EF4, one of WinForm and one ASP.NET MVC web application.  I have a problem with connections string and configuration.</p>
  
  <p>Is there a updated solution using VS2010/EF4/.NET Framework 4.0?</p>
