Ionide-vscode-fsharp: No intellisense, code lens or F# Explorer view v

[richardjharding]

No Intellisense , hover showing, cannot display either the F# Explorer side view or the info panel - all of the above used to work

windows 10
VSCode v 1.36.1 (user setup)
Ionide 4.0.6 but have also tried reverting to 4.0.4
Dotnet sdk 2.2.301

With verbose logging switched on I have the following example messages:

[LSP call] TextDocumentHover
[LSP] PositionHandler - Position request: d:/Source/Repos/RevocationOrchestration/TokenRevocation/configurationSettings.fs at (17,10)
[FSharpChecker] Current Queue Length: 0
[Checker] TryGetRecentCheckResultsForFile - d:\Source\Repos\\RevocationOrchestration\TokenRevocation\configurationSettings.fs
[LSP] PositionHandler - Cached typecheck results not yet available
[Error - 20:58:26] Request textDocument/hover failed.
  Message: Cached typecheck results not yet available
  Code: -32603 

This doesn't appear to be related to unexpected char in path to file

I'm also seeing with same in vs code insiders with the ionide experimental extension so I think its environment but I'm not sure what else to check in terms of processes that should be running or pre -reqs

Hello,

I had the same issue.
I solved it by deleting all .ionide folder above my workspace.
Deleting .ionide only in workspace root was not enough

Hey, I'd start with removing the .ionide folder as suggested by @rfrerebe and with removing any bin and obj folders in your project folders.

Hello,

Also if you have a sln file in your directory without your FSharp project,
it could also create this issue.
Solution is either to add fsproj to sln

dotnet sln add ./path/to/fsproj

Or remove sln file...

If you happen to work on csproj in Visual and fsproj in vs code, Visual
will create a sln for you and Ionide will stop working. I believe this is
by design, but it’s easy to forget this ...

Yes, sln behavior is by-design, indeed. If we detect sln file in workspace we load that by-default, otherwise we try to find all fsproj files in the workspace.

When I updated to 4.4.0, I have no intellisense / line lense / tool tips at all. Switches FSAC to core / netfw didn't have any effect.

I can reproduce this very easily: Create a new folder, open that in VSCode, create an empty fsx file and paste this code:

```open System

let x = 42

F# output:

[Error - 10:16:34] Request textDocument/documentSymbol failed.
Message: File 'c:\Temptesttest.fsx' not parsed
Code: -32603
[Error - 10:17:37] Request textDocument/hover failed.

@ronaldschlenker, should be working again in 4.4.1

[ronaldschlenker]

Wow, thanks @Krzysztof-Cieslak. That was quick. After Christmas, I try to finally set up a running dev environment for Ionide, so that I'm able to contribute some smaller things from time to time. Thanks again for your work. I have open collective donation on my TODO list for this year :)

[ronaldschlenker]

From my POV, you can close this. It's fixed.
