title: Scan solution on build, update text file
body: <p>We are using PostSharp aspects to abstract a config file. For example</p>
  
  <pre><code>    [Configurable(Default = "MyValue")]
      public static string value { get; set; }
  </code></pre>
  
  <p>Will have its getter/setter overridden by Postsharp to pull from a config file each time it is accessed.</p>
  
  <p>The problem is we have to manually create the config file, which can be tedious on large apps.</p>
  
  <p>What would be the best way to generate this config file at build time? I would need to scan all .CS files in the solution and generate the config file entries based upon what I find.</p>
