The latest version of the LinterCop Preview version seems to have problems with the preview version of the AL Language extension.

AL Language Extension Version: v14.0.1002061 (pre-release)

I've downloaded the latest LinterCop DLLs.

I copied the DLL BusinessCentral.LinterCop.AL-14.0.1002061.dll to BusinessCentral.LinterCop.dll

I closed all VS Code sessions.

Is there anything I did wrong in the manual process to use the correct LinterCop Version?

[Arthurvdv]

You did everything right, unfortunately the rule indeed needs some rework for the new version of the AL Language.

Note: We're created a new release of the LinterCop and the VS Code extension, where you now no longer need to manually copy .dll files anymore, see https://github.com/StefanMaron/BusinessCentral.LinterCop/issues/592#issuecomment-2095977402 and https://github.com/StefanMaron/BusinessCentral.LinterCop/issues/580#issuecomment-2095975595.

I'm going to close this issue, where I believe it's resolved with the latest update of the LinterCop (combined with the VS Code extension) to handle this.

@Arthurvdv can you maybe reopen this issue. This issue is back for our NextMajor Pipelines:

VSIX: 14.0.1070882

@Arthurvdv I must have been blind. The error looks pretty similiar, but is a little bit different:

Unhandled exception. Unhandled exception. System.InvalidCastException: Unable to cast object of type 'Microsoft.Dynamics.Nav.CodeAnalysis.Syntax.VarSectionSyntax' to type 'Microsoft.Dynamics.Nav.CodeAnalysis.Syntax.GlobalVarSectionSyntax'.

The function FindGlobalVariables instead of the function FindLocalVariables is the problem this time.

[Arthurvdv]

@pri-kise , I see now I added an LC0000 for the FindLocalVariables the last time, where I was hoping for a small code sample to reproduce this error. In the pre-release version of the LinterCop I now also added this to the FindGlobalVariables.

Can you see if you have a LC0000 diagnostic on this? Would be great if you could share a small code sample on this.

[pri-kise]

@Arthurvdv thanks for your fast response. I tried to reproduce the error and now it's gone.

During my research I found out, that we are having problems with our Download Script. We currently only Download the normal BCLintercopp.dll and not the BCLinterCop.next.dll. Therefore the next DLL wasn't up to date. After manually replacing the next DLL the error was gone.

I will close this issue for now. Thanks for you help.

[Arthurvdv]

No problem! I'm going to remove these LC0000 diagnostic for now (to reduce the Try/Catch).

P.S. I'm thinking of obsoleting the BusinessCentral.LinterCop.next.dll artifact in the future, because this is the same as the BusinessCentral.LinterCop.AL-PreRelease.dll.

[pri-kise]

a good to know. I wasn't aware of that. Hopefully not in the next months during summer holdiay, because we're still relying on this artifact.

[Arthurvdv]

Absolutely not during the holiday season (juli/august), probably somewhere 2025 I guess.

I’ve posted an issue to be made this generally known.
