Internet users have pulled out the pitchforks and are once again at odds with Microsoft regarding telemetry data, but this time around, it's because the company updated Visual Studio 2015, which is now adding secret telemetry code in the C++ binaries compiled by every developer.
The issue surfaced in May
on Reddit, when a user noticed a function named "telemetry_main_invoke_trigger" added to every binary he compiled for his private projects.
The user tested and discovered this happening with Debug and Release-level binary builds, on both Windows 7 and Windows 10.
Microsoft failed to document the Visual Studio telemetry codes
What worried Reddit users was that there was no documentation for these calls, either online or in the software's built-in documentation package.
