Changing some .cpp file did not lead to recompiles after pressing F7 (build). Only Rebuild the complete solution helped. Restart of VisualStudio and even restart of complete computer didn’t help.

I crawled the web (stackoverflow, Microsoft, …) and found some “solutions” (https://developercommunity.visualstudio.com/t/sometimes-visual-studio-is-not-detecting-changes-i/272741) which unfortunately didn’t fit for me.

1. I was NOT having a wrong system time on files
2. Reinstalling VS was no choice

So I found it for myself:

Solution:

Delete the TLOGs all.

There is a path to intermediate files (not .exe, but where the .obj are located)

\x64\<Debug|Release>\.tlog

Delete this directory!

Alternativly to make it easier you can delete the complete “x64” directory.

In my case everything worked fine afterwards.
