How do I enable syntax highlighting for a large C# file in Visual Studio Code?

Question

I'm used to using Visual Studio 2017, but need to view, and possibly edit, a large generated C# file which crashes Visual Studio (both 2015 and 2017) if I open it.

The VS crash is a separate issue, but I have found I can open the file in Visual Studio Code and at least view the source without Code crashing.

However, the normal syntax highlighting seems to be turned off, although I have the recommended "C# for Visual Studio Code (powered by OmniSharp)" extension from Microsoft installed and smaller files correctly show syntax highlighting.

As almost a complete novice in using VSCode, how do I enable highlighting when it doesn't get turned on by default? For info, the generated file is about 1.1 million lines of C#.

This could work:

"editor.largeFileOptimizations": false,
"files.maxMemoryForLargeFilesMB": 16384,
