  VS Code is built to handle smaller dependent projects instead of a large project, however if you see the base application is not split yet into components that allow managing the code in smaller projects. I recommend the following settings to increase the performance.
   Open settings.json file in the project or from global settings.  - To turn     off code analysis completely - "al.enableCodeAnalysis":     false
  - To turn     off running code analysis in the background     - "al.backgroundCodeAnalysis": false
  - To turn     off AL Code Actions - "al.enableCodeActions": false
  - To allow     the compiler to reuse the existing background compilation     - "al.incrementalBuild": true
  - To turn     off code lens - "editor.codeLens": false
  - To turn     off formatting when saving a file - "[al]": {     "editor.formatOnSave": false }
    In addition to the above settings, you can consider excluding the source folder of VS Code and the Microsoft.Dynamics.Nav.EditorServices.Host.exe from Windows Defender analysis.  |
