False errors appear in source file after editing it

[skalinets]

After editing of fs file it gets highlighted with errors, but still compiles.

Steps

1. Open vscode.
2. Create new expecto project using Ionide, build it
3. Open Tests.fs
   • Note that no errors are highlighted
4. Change open Expecto to open Expect
   • Errors appear (as expected)
5. Revert your change.
   • Errors are still there. Autocompletion is broken.

Looks like there is some problem with fsproj file, can you post it too.

here it is https://gist.github.com/skalinets/9dfe09092161c89c0daf517fbbf39647

But the project was generated by Ionide / forge. I did not touch anything there.

[Krzysztof-Cieslak]

Yeah, I can't see anything suspicious there.

In %USERPROFILE%\.vscode\extensions\Ionide.Ionide-fsharp-2.19.5\bin there should be FSharp.Compiler.Service.ProjectCrackerTool.exe

Try to run FSharp.Compiler.Service.ProjectCrackerTool.exe --text <path_to>/<my_project>.fsproj true

C:\Users\admin\.vscode\extensions\Ionide.Ionide-fsharp-2.19.5\bin> .\FSharp.Compiler.Service.ProjectCrackerTool.exe --text C:\Users\admin\work\fst\exptests\exptests.fsproj
{ProjectFile = "";
 Options = [||];
 ReferencedProjectOptions = [||];
 LogOutput = "At least two arguments required.";}
C:\Users\admin\.vscode\extensions\Ionide.Ionide-fsharp-2.19.5\bin> .\FSharp.Compiler.Service.ProjectCrackerTool.exe --text C:\Users\admin\work\fst\exptests\exptests.fsproj true

Process is terminated due to StackOverflowException.

You have VS2017 RC installed by any chance? I guess it's duplicate of #291

[skalinets]

yes, I do have it installed.
Regarding duplicate -- #291 refers to fsharp/fsharp-compiler-docs#672 that in turn gets reproduced when project filename contains dots. Mine does not.

I just checked my VS2017 and it seems have new update 15.0.26014.0 --> 15.0.26020.0. Will give it a chance :)

[skalinets]

OK, I uninstalled VS2017 and issue has gone. I think this issue can be closed as a duplicate of #291. Thanks.
