title: Using Deedle with .NET 4.0
body: <p>Is it possible to use Deedle if I'm stuck with .NET 4.0, VS 2010 and Windows 7?</p>
  
  <p>Currently it's complaing that I need FSharp.Core 4.3, but I only have 4.0 available.</p>
  
  <p>Maybe an older version of Deedle somewhere?</p>
  
  <p>I have to replace some scripts that use Python Pandas with C#.</p>
