Error: input.fsx (1,1)-(1,1) typecheck error The module/namespace 'System.IO' from compilation unit 'System.Runtime' did not contain the namespace, module or type 'FileInfo'

Describe the bug

Please provide as much information as you can.

Ever since I updated my project to .net6.0, dotnet-interactive no longer runs my code. Instead I get the following error when running a cell:

Error: input.fsx (1,1)-(1,1) typecheck error The module/namespace 'System.IO' from compilation unit 'System.Runtime' did not contain the namespace, module or type 'FileInfo'

Obviously, System.IO does define FileInfo. Of note, if i comment out the last line, the error disappears.

Also, this code works fine in FSharp Interactive.

How should I go about debugging / getting to the bottom of this? Thanks for any help.

Please complete the following:

Which version of .NET Interactive are you using? There are a few ways to find this out:

$ dotnet interactive --version

Can you paste the version that VS Code reports when you run #!about? Both in VS Code and VS Code - Insiders.
