title: How to not load unused assemblies
body: <p>ASP.NET MVC4 application does not use Oracle Client.
  List of loaded assemblies is determined using</p>
  
  <pre><code>var sb= new StringBuilder();
  var i = 0;
  foreach (var a in AppDomain.CurrentDomain.GetAssemblies().Where((asm) =&gt; asm.GlobalAssemblyCache))
              {
                  sb.Append(++i);
                  sb.Append(' ');
                  sb.AppendLine(a.FullName);
              }
  </code></pre>
  
  <p>Result is below.
  It shows that System.Data.OracleClient assembly is loaded. 
  Solution does not contain reference to this assembly.
  It lookes that there are other unused assemblies such as  SMDiagnostics , DataVisualization etc.</p>
  
  <p>Why those are loaded ? How to find unused assemblies and disable their loading ?
  Web application is running is Virtual Private Server with limited RAM and not loading those hopefully frees some memory.</p>
