Erel's says: " The long GUID id (cc7c8eddb7024f38a1b4491ef214b8f7) should be changed whenever you make a new release. It uniquely identifies the build. You can change one or more of the hex digits. "
Can I use this GUID of the example in all my projects or I need create a new GUID for each one (and only change the digits in new build)?
