Add-BindingRedirect doesn't change App.config though it should

Question

I published nuget package here. It is basically one .net assembly witch

• references FSharp.Core 4.3.1
• references FParsec
  • that references FSharp.Core 4.0.0.0 (!)

All pretty straightforward.

Now when I add the package to a new VS2013 C# project, it doesn't add the tag to the app.config, meaning it crashes at run-time with "Could not load file or assembly 'FSharp.Core, Version=4.0.0.0 ..." message.

If add add the tag manually it works. Add-BindingRedirect command doesn't do anything either. Apparently it doesn't see the issue with FSharp.Core.

What am I doing wrong? Should I add a hint somewhere that the tag for the FSharp.Core is needed?

NOTE: following the references you can download the *.nuspec file as well as find the git repository and appveyor build.
