Can't run F# after updating Visual Studio 2017

I just updated my Visual Studio 2017 installation to the latest version (15.6.0) and now I'm unable to run F# script. When I try a dialog box says that "fsc.exe has stopped working" and the following message appears in LINQPad:

"Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'FSharp.Compiler.Private, Version=4.4.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
at Microsoft.FSharp.Compiler.CommandLineMain.main(String[] argv)"

I tried with the latest release and the latest beta of LINQPad, both have the same behavior.

Comments

  • Can you successfully invoke fsc.exe from the command-line?
  • Yes, it works. I tried with this one:
    C:\Program Files (x86)\Microsoft SDKs\F#\10.1\Framework\v4.0\fsc.exe
    which is the latest installed and pointed by the env variable:
    FSHARPINSTALLDIR
    I tried to compile an hello world file:
    C:\Program Files (x86)\Microsoft SDKs\F#\10.1\Framework\v4.0>fsc.exe test.fs
    Microsoft (R) F# Compiler version 10.1.0 for F# 4.1
    Copyright (c) Microsoft Corporation. All Rights Reserved.
    Furthermore I have no issue using F# into Visual Studio 2017.

    Here is the crash report, it seems LINQPad doesn't use the latest F# compiler version:
