Syntax highlighting, Find usages and Go to definition (F12) while in code review diff

[objecttothis]

Is your feature request related to a problem? Please describe. I can't use some of the features of VS syntax highlighting (spelling errors, unused code, etc) and navigation and that's one of the bigger reasons why doing a code review inside of VS is appealing.

Describe the solution you'd like Please make it so that I can use find usages and Go to definition (F12) and see the VS syntax highlighting for errors to catch problems in the code while inside the diff that gets opened when double-clicking the changed file to perform a code review.

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.
