JetBrains Rider 2023.1 Help

Code Inspection in F#

JetBrains Rider's code analysis in F# is provided by the F# Compiler Service. Nevertheless, the key code analysis features supported in C# and VB.NET (except for quick-fixes) are also available in F#. For detailed information on these features, refer to the Code Analysis section where you'll also find useful keyboard shortcuts.

Enable the F# Support plugin

This functionality relies on the F# Support plugin, which is bundled and enabled in JetBrains Rider by default. If the relevant features aren't available, make sure that you didn't disable the plugin.

  1. Press Ctrl+Alt+S to open the IDE settings and select Plugins.

  2. Open the Installed tab, find the F# Support plugin, and select the checkbox next to the plugin name.

Code inspection

The analysis is performed by applying code inspections to the current document or in any specified scope.

Solution-Wide Analysis
