If syntax highlighting is supported in the code view, it should be customisable to the user's preferred VS syntax highlighting scheme. Ideally, the default settings would be imported automatically from VS; afterwards, they could be changed by importing a color scheme, e.g., from http://studiostyl.es/.
The code view is going to show an inline diff; combining this with syntax highlighting would be difficult. For now, I'm going to assume that syntax highlighting will not be shown in the code view.
