	Thanks for the post. The article has been updated. Quote: In more recent IDE's such as Vs2017/2019 use "Add Existing Item" which automatically creates the link to the source. Tip: After you add files, click the file and press F4 to see if a file is local to the project or shared.

	Use shared projects for cpp/h code. Use add existing for .ino code. Documentation Available Here

	You can add #includes for libraries to shared projects and they will be discovered. If you don't know which includes to add then add the library to your .ino and then grab the #includes. You can remove the #included from the .ino after that but they will not do any harm. If you need more help it is important to show the code you have used to add #includes to your add existing > shared code.

	Yes that is best, but also on the vMicro>Compiler menu you can enable the project folder -I include. This would then mean that the project folder is a compiler include path and .h files can be referenced as relative paths from that point... For example:- Project with include path = c:\foo\bar\MySketchProject Allows for "..\SomeBarFolder\MyHeaders\Header1.h" Allows for "..\..\SomeCFolder\MyHeaders\Header1.h" Using the include path applies only to headers (.h). Files that need to be compiled to object files such as .cpp must be in shared project or the project.
