In Visual Studio 2013 SP 4 there is no problem adding a SCSS file and syncing on every save. I got confused when syncing failed, I found the problem was using a variable before it was defined. The SCSS file doesn't show any error but sync fails.
This works for sync:
$body-main: 45px;
body {
padding-top: $body-main + 25px;
padding-bottom: $body-main - 5px;
}
This doesn't work for sync
body {
padding-top: $body-main + 25px;
padding-bottom: $body-main - 5px;
}
$body-main: 45px;
In the second case there are no errors and intellisense works, but sync fails.
