.NET 6 NullReferenceException #1629

Closed Ciantic closed 2 years ago

Ciantic commented 3 years ago

Describe the bug

The .NET 6 support was closed, so I'm not sure what the issue is. With .NET 6 brand new project, Intellisense is broken, I get errors and NullReferenceException:

[Error - 14.15.18] Request textDocument/codeAction failed.
  Message: System.NullReferenceException: Object reference not set to an instance of an object.

Additionally I get error like this: No .fsproj or .fsx file references c:\Source\FSharp\testgraphql\Program.fs

Steps to reproduce

  1. Install .NET 6
  2. Clone this: https://github.com/Ciantic/bug-fsharp-with-graphql
  3. Open in VSCode

Expected behaviour

No errors, and intellisense works.

I can't reproduce this anymore, I have among other things installed .NET 5 SDK. Nuked my nuget cache etc. When I could reproduce this I only had .NET 6 SDK installed.

Feel free to close this if it's not an issue, but perhaps NRE could be catched if it makes sense, and if someone else can reproduce this.

I'm experiencing the same issue, since I installed .NET 6 sdk Ionide stopped working completely. Ionide Version 5.10.2

Ionide works just fine with .NET 6 - actually, it's the version we require for Ionide right now. Closing.
