How do I change the colouring of preprocesor #if'd code in a Xamarin project in Visual Studio 2015?

Question

I am using a Xamarin solution (VS2015), with shared code then a separate project for UWP, IOS and Android.

In the shared project, how do I change which code is greyed out when using #if?

e.g:

#if (WINDOWS_PHONE || WINDOWS_UWP || WINDOWS_APP)
    StorageFolder storageFolder = Windows.Storage.ApplicationData.Current.LocalFolder;
    StorageFile sampleFile = await storageFolder.GetFileAsync(fileName);
    string text = await FileIO.ReadTextAsync(sampleFile);
    return text;
#elif (__IOS__ || __ANDROID__)
    var documentsPath = Environment.GetFolderPath(Environment.SpecialFolder.Personal);
    var filePath = Path.Combine(documentsPath, fileName);
    return await Task.Run(() => File.ReadAllText(filePath));
#endif

Currently the __ANDROID__ section is being colourised by VS, and the WINDOWS_PHONE part is greyed out. How can I tell VS that I want it the other way around?

Drop down this box and select the appropriate project to run, in your case, the UWP project
