title: How can I use the objects ConnectionStringSettings and ConfigurationManager into my C# - NUNIT project?
body: <p>I'm trying to apply the solution proposed in this question: <a href="https://stackoverflow.com/questions/3164251/using-the-connectionstring-in-an-nunit-test">Using the connectionstring in an nunit test</a> but I can't seem to find the <code>ConnectionStringSettings</code> and <code>ConfigurationManager</code> objects in the new Framework 4.5.</p>
  
  <p>I added the namespace: <code>System.Configuration</code>. Where acording <a href="http://msdn.microsoft.com/en-us/library/system.configuration.connectionstringsettings.aspx" rel="nofollow noreferrer">Microsoft Documentation</a> is supposed to be. But Visual Studio still cant find it.</p>
  
  <p>Could anyone here give me a hand with this?</p>
