I have a c# project that is targeting net7.0. I have a block code that should only run when running on windows. And I am developing on Windows. To that end, I’ve added #if...#endif

#if WINDOWS

using var el = new EventLog("Application");
el.Source = "Application Error";
el.WriteEntry(ex.ToString(), EventLogEntryType.Error, 10002);

#endif

However, when I run it locally in Visual Studio 2022, the code inside the block is grayed out and does not run at all.

How do I mark it so that it only runs on windows?
