title: keyword not supported data source
body: <p>I have an asp.net-mvc application with the default membership database. I am accessing it by ADO.NET Entity Framework. </p>
  
  <p>Now I want to move it to IIS, but several problems showed up. I had to install SQL Server Management Studio, Create new DB, import there all the data from the previous .MDF file. Only thing left to do (as far a I know) is to change to connection string. However, I am not really experienced with this and keep getting the Keyword not supported: 'data source'. exception. Here is my connection string:</p>
  
  <pre><code>&lt;add name="ASPNETDBEntities" 
       connectionString="Data Source=MONTGOMERY-DEV\SQLEXPRESS;Initial Catalog=ASPNETDB;Integrated Security=True;" 
       providerName="System.Data.EntityClient" /&gt;
  </code></pre>
  
  <p>Any ideas, what's wrong?</p>
