	Hi. I have installed Visual Micro extension v1810.4.0. After that I have opened an arduino project I had working. This project contains next macro definition Code (C++) #define buildTube(id) \ Tube tube##id ( ptrValve##id , ptrPressureTransducer##id) When I have tried to compile it, console output showed an error like: dl-190.ino: 41:10: error: stray '##' in program Tube tube##id ( ptrValve##id , ptrPressureTransducer##id) However, If I delete backslash and define macro in one line Code (C++) #define buildTube(id) Tube tube##id ( ptrValve##id , ptrPressureTransducer##id) build works as expected and success is shown at console. If I try to compile this project with Arduino IDE and VSCode with arduino plugin, build process runs without error. What could be the reason? I need the ability to define multiline macro because I have many others bigger. Thanks and regards.

	Hi and thanks for reply. VMicro -> Compiler -> Deep Search is enabled. Arduino IDE version is 1.8.7. I forgot to say that I have Visual Studio 2017 Community Edition (version 15.8.6). Regards.

	Do you have this issue in "Release" build mode?

	This will be resolved when we add support for better prototype extraction and ctags over the next few months. In the meantime please try to put these defs in a .h files then #include that in the .ino Thanks for the report.
