title: EDMX .NET 4.5 to 4.0?
body: <p>We're using the Entity Framework and we created our EDMX when our project was set to build .NET 4.5. Now we want to switch to .NET 4.0 but when we do, we get compilation errors for the EDMX file.</p>
  
  <p>It states the following error:</p>
  
  <pre><code>Error 10027: The XML namespace for the conceptual model's schema element is not supported on this project's target framework version.
  </code></pre>
  
  <p>Is there any solution other than recreating the EDMX file?</p>
