System.MissingMethodException: Method not found: 'Microsoft .FSharp.Core.FSharpFunc`2

I've got a problem when launching a Canopy test in a Windows box:

Unhandled Exception: System.MissingMethodException: Method not found: 'Microsoft
.FSharp.Core.FSharpFunc`2<System.String,System.String> canopy.core.get_xpath()'.
at <StartupCode$UITest>.$Program.main@()

I guess this is because when compiling it, my Visual Studio 2012 restored Nuget packages and spitted this in the console output:

Consider app.config remapping of assembly "FSharp.Core, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" from Version "4.3.0.0" [C:\Program Files (x86)\Reference Assemblies\Microsoft\FSharp\3.0\Runtime\v4.0\FSharp.Core.dll] to Version "4.4.0.0" [C:\Users\Andres\Documents\Code\endtoendtests\packages\FSharp.Core.4.0.0.1\lib\net40\FSharp.Core.dll] to solve conflict and get rid of warning.

How to exactly add this remapping to fix this problem?

Managed to get it to work with this App.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="FSharp.Core" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
        <bindingRedirect oldVersion="4.3.0.0" newVersion="4.4.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

This must be because I've never installed F#, so that I'm using the version that comes with my VS2012 (v3.0). I know I know, I should upgrade to 3.1, or 4.0 even.
