I am getting this error:
'LEDSkulptur_Dodo.ino: 18:1: error: expected unqualified-id before 'if'

I know normally it appears if you miss a semicolon or brace or something like that. But trust me, I did not. The code compiles well in the Arduino IDE but in Visual Studio/Micro it throws this error. 

What can I do to fix that?

Now it compiles, thank you!

I have had an exact same problem after my VS 2017 had crashed. It looks like, my .ino file was some-how damaged. There was no any visual evidence though. However, when I rewrote this .ino with another editor (it was vim), problem disappeared.
