Telemetry
---------
Microsoft Testing Platform collects usage data in order to help us improve your experience. The data is collected by Microsoft and are not shared with anyone.
You can opt-out of telemetry by setting the TESTINGPLATFORM_TELEMETRY_OPTOUT or DOTNET_CLI_TELEMETRY_OPTOUT environment variable to '1' or 'true' using your favorite shell.
