I am trying to run a script in the fsi. I get the following error.

Could not load file or assembly 'FSharp.Core, Version=4.3.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

I found the following references that suggest I may have to update the default FSharp.Core version somewhere inside Visual Studio, downloading the package with nuget is not enough.

I am not sure how to fix this and I am afraid to permanently damage the vs configuration.

You can see where FSI is located by typing 

System.AppDomain.CurrentDomain.BaseDirectory;;

In my computer I get

C:\Program Files (x86)\Microsoft SDKs\F#\3.1\Framework\v4.0\

And I have a file

Fsi.exe.config

which does the redirects.

You probably point to an old FSharp installation, as 4.3.0.0 and 4.3.1.0 should be binary compatible.

  • Thanks. After restarting VS, the script now executes but IntelliSense still doesn't work properly. – NoIdeaHowToFixThis May 01 '14 at 07:04
  • oh there is no intellisense in fsi if that is what you refer to. the way to use it is to type your script in fsx file, in the editor, then hightlight and alt + enter. that sends the text area in FSI – nicolas May 01 '14 at 08:38
  • Yes, I know, thanks. Sorry, my question got messy with the latest edit. Now the script runs properly in the fsi but IntelliSense in the Visual Studio editor, where I type my script, is not working. – NoIdeaHowToFixThis May 01 '14 at 08:45
  • I have reverted back to the old version of my question.. the updated edit was confusing at most. – NoIdeaHowToFixThis May 01 '14 at 08:47
