You could also probably try using JetBrains's CLion with Qt, or only Qt (C++).
CLion CMake's projects are also detected by Windows Defender, but the final executable isn't.
For C#, you could try JetBrains's Rider. It doesn't require Visual Studio installed, only .NET.
After all, it's getting detected. I haven't used this patcher in almost 2 years. I made a fresh compilation just in case.
I'm currently using the patcher I made in Electron, it isn't being detected.
"It is not patcher's fault." I know, I'm used this for years, even the same exe what had 2 alerts goes to 15+ as of today.
I read that microsoft answers page but looks like there's no solution for this problem?
Can you upload your compiled patcher for me or tell your server's url? I'm just curious if it had the same false positive rate.
