Disable CSS auto-format in Visual Studio (particularly 11)

It doesn't look like there's an option. I checked through the registry settings being accessed and couldn't see anything there for it either.

I'd suggest you raise an issue on the connect site or add an entry to the Visual Studio User Voice site.

Here is how with SCSS. I belive it will be a similar process with CSS.

In my case I am using Asterisk AEL which is a custom script from Asterisk. Ael looks like this https://wiki.asterisk.org/wiki/display/AST/AEL+Loops

Anyways I first had to format .ael file extension as SCSS by going to Options then searching for file extensions.

Because AEL code is not SCSS I then searched for SCSS on options and disabled mostly everything as:

Now visual studio will not mark errors and will still format the code.
