title: C# Common Library
body: <p>I'm hoping to find an open source .net common library, but I'm having a hard time finding one.</p>
  <p>What I'm looking for a is something that contains : Logging, Caching, String Manipulation, Config Reading, ext?!?.</p>
  <p>Do you know if anything like this exists or is this more likely something that I will need to create myself?</p>
