Your environment

Output of haskell-language-server --probe-tools or haskell-language-server-wrapper --probe-tools:

I'm using stack under WSL on Windows 10. From where should I run haskell-language-server?

Which OS do you use:
Windows
Which lsp-client do you use:
vscode

Here's some debug output I captured after turning on tracing for the Haskell vscode extension:

This one is probably because they are in different sections in the cabal file (I guess your Main module is for executable and Lib module is for library), not because they are in different modules.

This is possibly a duplicated of #1822

Related issue: #735

@dharmatech many thanks for reporting the issue providing all the necessary info we ask for.
Like @Ailrun, i think this seems to be a duplicated of #1822. Gonna close this one, @dharmatech feel free to reopen if you think your issue differs in some way

@Ailrun,

This one is probably because they are in different sections in the cabal file (I guess your Main module is for executable and Lib module is for library), not because they are in different modules.

Yup, that's exactly right! I've included the cabal file below.

This is possibly a duplicated of #1822

Related issue: #735

Thank you! I will follow those.
