title: Cannot generate ADO.NET Model classes
body: <p>I am using <strong>Visual Studio Express 2012 for Web</strong>.</p>
  
  <p>I have created a new empty web site using <strong>.net framework 4</strong>.</p>
  
  <p>I am using <strong>SQL Server 2008 R2 Service Pack 2</strong>, and I have a database with 4 tables there.</p>
  
  <p>When I try to add a new ADO.NET data model into my website from this database, the Model.edmx, Model.tt, and Model.Context.tt files are all generated, but my <strong>Model.cs and Model.Context.cs files are missing</strong>. If I try to use the option 'update the model from database' nothing happens. </p>
  
  <p>I have installed Visual Studio just two days ago, and initially I could work with a successfully generated model for another web site. But now I cannot generate the model in any website. I have tried with other databases, to no success.</p>
