Running the local core Turnkey app is a great way to shorten the development loop.

One issue you may not want is having your source code for SCSS, CSS, and EXT_Components inside the Turnkey core file tree - but they must be found there by the web server. This can be addressed with the standard Windows function of symbolic links for directories or files:

mklink /d C:\<turnkey core location>\EXT_Components\MoveAroundInGrid C:\<source code location>\EcoProject1_AssetsTK\EXT_Components\MoveAroundInGrid

To break a symbolic link, call rd c:\<link to break>
