error while creating a fsi session
StefanBelo opened this issue · 6 comments
When debugging my app in VS (debug or release version) all works fine. After installing the released app it throws exception: "error while creating a fsi session"
What could go wrong?
I tried to run the app in admin privileges, but the same error occurs.
It's very likely that after installing the app we cannot find a FSharp.Core.dll. We try hard to find one. You can either distribute it (make sure to distribute .optdata and .sigdata as well). Or install the FSharp package.
But this is just guessing. For further insight you need to provide additional exception information (Stacktrace, the full message, inner exception ...).
My app is actually wpf app fully written in F#. FSharp.Core.dll is in app directory, it is 4.4.0 version. Maybe that is a problem, as your assembly and FSharp.Compiler.Service is older version?
In exception message I can see Output:
F# Interactive for F# 3.1
What assemblies should I include to the installation?
Here is full exception message:

I am sorry, you actually replied. Both .optdata and .sigdata should be included, now it all works, so fsi.exe is used or not?
In error message:
Input: Fsi Arguments: [|""C:\fsi.exe""; ""--noninteractive""|]
On my dev machine fsi.exe is included with VS, but it hardly be on users machines.
No fsi.exe is not used (the output is the same as from FSI, because FSharp.Compiler.Service shares the same code-base). So this can be closed?
Thanks for your help, it can be closed.
You are welcome!
