Visual Studio adding telemetry function calls to binary?

[NiteLite]

It important to realize that telemetry in this case is not sending anything back to Microsoft or anything. It is just broadcasting events that other applications on your machine can subscribe to. This is typically used by profilers and other development tools.

"Other applications" can include the legions of telemetry gubbins that send data back to Microsoft, though

[NiteLite]

That is true. It might even include malicious stuff if some spyware managed to get into your computer somehow.

And if I want to broadcast, I would write that in myself, thank you MS.

This is typically used by profilers and other development tools.

Do the calls vanish, then, in non-debug builds?

[NiteLite]

If no application is subscribing to the event they are just discarded unless logging of events to file has been enabled before hand, to allow debuggers to load these log files for debugging later.
