Common

Telemetry

Starting with this release (v34.2.2), Syncfusion WPF UI Component Suite introduces telemetry (development-only) to help us better understand product usage, feature adoption, usage trends and make better product roadmap decisions.

Telemetry is enabled by default and collects only a limited set of anonymous usage data while applications are running in a development environment. Telemetry is automatically disabled in production environments, and no telemetry is collected from deployed production applications or end users. For more details regarding telemetry, please refer to this link: [Essential Studio Telemetry Common Syncfusion](https://help.syncfusion.com/common/essential-studio/telemetry)

Since telemetry has been added as a dependency to all our controls, it is mandatory to include the telemetry assembly in your project whenever you use any of our control assemblies.
