Currently our hot reload takes a looong time (over 20 seconds). This is because its tracking changes over 50+ class libraries (I think), while we really only change 1 project.
Is it possible to somehow exclude these projects from hot reload to make it perform faster? On new projects it's so unbelievably fast.
The only solution I've found is to disable hot reload in launchSettings.json which would turn the feature off.
The answer is NO.

No such sub feature you want.
