To enable syntax highlight for unity shaders in Project Rider, download this file and put it into your "filetypes" folder.

Windows Vista, 7, 8, 10:
<SYSTEM DRIVE>\Users\<USER ACCOUNT NAME>\.Rider10\config\filetypes

Mac OS X:
~/Library/Preferences/Rider10/config/filetypes

Linux:
~/.Rider10/config/filetypes

On Mac, works well with following path.
~/Library/Preferences/Rider10/filetypes

I've added cginc as an extension type:

<extensionMap>
    <mapping ext="shader" />
    <mapping ext="cginc" />
  </extensionMap>

@bbeaumont, thanks for catching this! Added cginc to the exetension map.

For the latest version of rider on Mac, the path for the syntax highlighting .xml has changed to:

~/Library/Preferences/Rider2017.1/filetypes

Thx!
Now rider support shaderlab highlighting out of the box.
