Hi,

If you are using arduino compatible projects then you do not need to check the .vcxproj into source control

This is because Arduino doesn't need a project. Visual Micro only uses the project to ensure the correct intellisense and as you see the file is updated each time it opens and also each time you add libs etc. If you think about it this has to make sense because you do not set include or tool "paths", they are always automatically recalculated from the current locations of each pc so that the VS intellisense can work.

It turns out that each developer installs libraries and arduino ide on different drives and/or locations. Therefore relative paths will not work across multiple machines and need to be rebuilt for each pc.

If you are working outside the arduino standard, with local libraries, short cuts to shared sources, with code in sub folders other than the \src folder or with global defines that are not configuration specific then you will need the vcxproj in source control.

Once you understand the dynamic nature of arduino paths, if you can suggest a better way to work then feel free to make a suggestion as this is always being reconsidered.
