title: "Consider app.config remapping of assembly ..." warning in F#
body: <p>After I installed VS11, I started to get the following error:</p>
  
  <blockquote>
    <p>Consider app.config remapping of assembly "FSharp.Core, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" from Version "2.0.0.0" [C:\Program Files (x86)\Reference Assemblies\Microsoft\FSharp\2.0\Runtime\v2.0\FSharp.Core.dll] to Version "4.0.0.0" [C:\Program Files (x86)\Reference Assemblies\Microsoft\FSharp\2.0\Runtime\v4.0\FSharp.Core.dll] to solve conflict and get rid of warning.
    C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(1490,5): warning MSB3247: Found conflicts between different versions of the same dependent assembly.</p>
  </blockquote>
  
  <p>What exactly should I do? I have no idea how to do such a remapping.</p>
