Code wrapped in defines not highlighting correctly with Unity

Environment data

VS Code version: 1.26 C# Extension version: 1.15.2 Unity version: 2017.3.1f1 .Net3.5 OS: Windows 10

Steps to reproduce

1. Create unity project
2. Create code with defined out code Ex. #if UNITY_ANDROID

Expected behavior

Code that is not being compiled due to defines should be grayed out

Actual behavior

Code looks normal or has incorrect highlighting. In the screenshot below the highlighting at the top is reversed because the RECORD_RAND_FLOAT_CALLS is not defined. Hovering works as expected with the defined out code not giving any results. You can also see towards the bottom that another #if #else has different behavior with the same define.

I’ve also looked at the Assembly-CSharp.csproj file and confirmed that it does contain a UNITY_ANDROID define but highlighting does not occur.

@XeonG This should be handed by semantic highlighting. Do you have csharp.semanticHighlighting.enable set to true in your vscode settings?
