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 it 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>
