title: Exception with SimpleMembership and ADO.NET Entity Data Model
body: <p>I create new ASP.NET MVC4 project with account controller uses forms authentification.
  Then I run project and register new user for creating database file.
  Then I create some tables in new mdf database file and I use ADO.NET Entity Data Model for this new tables instead of membership's tables.
  After creating model.edmx there are two connection strings in web.config file.</p>
  
  <pre><code>    name="Entities" connectionString="metadata=res://*/Models.Database.LAModel.csdl|res://*/Models.Database.LAModel.ssdl|res://*/Models.Database.LAModel.msl;provider=System.Data.SqlClient;provider connection string=&amp;quot;data source=(LocalDb)\v11.0;attachdbfilename=|DataDirectory|\aspnet-LAWebProject-db.mdf;initial catalog=aspnet-LAWebProject-db;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&amp;quot;" providerName="System.Data.EntityClient"

  </code></pre>
  
  <p>The project debugs few times then crashed with following exception:
