I use FsAutoComplete via vim-fsharp , but the same err

Which version of fsautocomplete are you using? Which versions of VS do

Hello <a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-ur

Note that it compiles fine with fsc and with <code cl

<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clip

Which version of fsautocomplete are you using?
Which versions of VS do you have installed, and which did you use to create this project file?
Please can you post the whole project file so I can try to reproduce?

Hello @rneatherway :) Thank you for the quick reply.

I'm using version 0.23.0 of fsautocomplete. EDIT: I checked and it doesn't work on 0.24.1 either.
Visual Studio Community 2015, Version 14.0.23107.0
The project file is nothing more than the fs file given above, used inside a template project (Visual F#: Console Application).

Note that it compiles fine with fsc and with MSBuild from the command line.
Also, the same error occurs in fsautocomplete even if I don't provide a project file:

fsautocomplete.exe
parse "Project.fs"
module M
open System.Diagnostics
let p = Process.GetProcessesByName "fsi"
<<EOF>>
{"Kind":"info","Data":"Background parsing started"}
{"Kind":"errors","Data":[{"FileName":"D:\\Code\\fsharp-repro\\FsAutoComplete-repro\\Project.fs","StartLine":2,"EndLine":2,"StartColumn":9,"EndColumn":16,"Severity":"Error","Message":"The namespace or module 'Process' is not defined","Subcategory":"typecheck"}]}

But no error if I try to use, for instance, System.Console.WriteLine:

fsautocomplete.exe
parse "Project.fs"
module M
open System
System.Console.WriteLine "hello world"
<<EOF>>
{"Kind":"info","Data":"Background parsing started"}
{"Kind":"errors","Data":[]}

from fsautocomplete.

Can you paste the output of the compilation from the command line, most importantly the arguments given to fsc by msbuild.

But a simple call to fsc Program.fs succeeds just as well.

OK, it does seem like a bug. I will have to try to reproduce in my VM, I'll post back here once I learn something. In the meantime, if you want to keep using VIM, I could recommend a few ideas that might help:

Try lowering the .NET Framework version to 4.5
Find a project file generated by VS2013 (there are examples in the http://github.com/fsharp/fsharp repo among other places)
Generate a project file using http://github.com/fsprojects/projekt

@yever I reproduced this using your project file. When I enabled more logging, I found that the issue was the absence of the App.config file referenced by the project. After I removed that entry from the project file, I received the following output:

@yever as far as I can tell this is just a problem due to the missing AssemblyInfo.fs, so closing for now. If that isn't the case let me know.
