In previous versions of VS I could press F5 to start a Debug session and if the code had changed slightly it'd give me the option to rebuild or not rebuild - but VS2019 always rebuilds without giving me any option.

Under Tools->Options->Debugging I disabled the option to Require source files to exactly match the original version but that doesn't seem to help. Is there some other setting that'd allow me to start a Debug session even if a few source files have changed slightly?
