System wide bindingRedirect for F# 4.0.0.0 to 4.3.0.0

I have some xUnit tests which are failing with the common

Could not load file or assembly 'FSharp.Core, Version=4.0.0.0, Culture=neutral, 
PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. 
The system cannot find the file specified.

To perform a machine-wide redirect, I added to the file

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config 

<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly>
      <assemblyIdentity name="FSharp.Core" publicKeyToken="b03f5f7f11d50a3a"
                        culture="neutral"/>
      <bindingRedirect oldVersion="4.0.0.0" newVersion="4.3.0.0"/>
    </dependentAssembly>
  </assemblyBinding>
</runtime>

Do you have a better way to deal with the 4.0 / 4.3 issue definitely ?
