Salesforce VS Code extension creates .sfdx folder in non-Salesforce project

[theperiscope]

Summary

This issue may be related to #6641. I observed that C#/.NET project all of a sudden had .sfdx folder under, which had to be manually cleaned up.

Steps To Reproduce

1. Use VS Code (Windows 11, latest SF CLI) with Salesforce extension pack
2. Open Salesforce-project and non-Salesforce project.

Expected result

The non-Salesforce project should not have Salesforce folders.

Actual result

Non-Salesforce project contained .sfdx folder with thousands of files.

Hello @theperiscope 👋 It looks like you didn't include the full Salesforce CLI version information in your issue.
Please provide the output of version --verbose --json for the CLI you're using (sf or sfdx).

A few more things to check:

• Make sure you've provided detailed steps to reproduce your issue.
  • A repository that clearly demonstrates the bug is ideal.
• Make sure you've installed the latest version of Salesforce CLI. (docs)
  • Better yet, try the rc or nightly versions. (docs)
• Try running the doctor command to diagnose common issues.
• Search GitHub for existing related issues.

Thank you!
