How to run JetBrains Rider in Internal Mode

The “Internal mode” is designed by Rider developers for testing purposes: it adds additional assertions and diagnostics and enables exception reporting. In production builds, exceptions are silently logged and not reported to the end-user. There is no need to turn “Internal mode” on for daily work, but Rider team members can ask a user to enable it to collect additional logs or dumps.

Via JetBrains Toolbox:

• Open JetBrains Toolbox
• Find JetBrains Rider
• Click on the ⋮ icon and select the Settings menu item:
• On the "Rider Settings" page, expand the Configuration node, hit the Edit JVM options... and append -Didea.is.internal=true to the end of the file
• Save your changes
• Run JetBrains Rider

Via JetBrains Rider:

• Open a solution in JetBrains Rider
• Open Help | Edit Custom Properties
• Paste idea.is.internal=true in the text field and save the change
• Restart JetBrains Rider

How to verify that Internal mode is ON

Rider will show the following internal menu items in the UI:

• View | Tool Windows | Internal
