These are performance counters for your app. Here is the image that describe them.

// Display the current frame rate counters.
// This is enabled by default in your app
Application.Current.Host.Settings.EnableFrameRateCounter = true; 

These are for monitoring your app. Like frame rates etc.For more info check this Reference.

Ctrl + F "Enable frame rate counters"
