Desired functionality.
ng serve watch and ng build --aot capability for symbolically linked modules on Windows machines.
This does not seem to be an issue on Linux machines.
Mention any other details that might be useful.
The same issues also occurs with modules linked by lerna. For example:

Known workaround for issue 5.1 with
ng serveng ejectmodules-> symlinksvalues inwebpack.config.jstofalsefilipesilva commentedon Aug 2, 2017
I believe the
--preserve-symlinksalready solves this (#6460).hieuxlu commentedon Aug 4, 2017
@filipesilva Thanks for your prompt response. I have updated to
@angular/cli@latest, which had the fix you mentioned.ng serve --preserve-symlinks=truedoes not watch changes in the symbolic linked folder anymore. Is this is an intended effect?ng build --prod --preserve-symlinks=true&ng build --prodstill failed though.Error log

That particular side effect intended per se... but it is by design, in a way. You can find more information about the problems in that sort of setup in #6387 (comment) and #6228 (comment).
