Version number of this object. A host can compare this to a stored version number to determine whether a project's XML has changed, even if it has also been saved since.

The actual value is meaningless: an edit may increment it more than once, so it should only be compared to a stored value.

Remarks

Used by the Project class to figure whether changes have occurred that it might want to pick up by reevaluation.

Used by the ProjectRootElement class to determine whether it needs to save.

This number is unique to the appdomain. That means that it is possible to know when a ProjectRootElement has been unloaded (perhaps after modification) and reloaded -- the version won't reset to '0'.

We're assuming we don't have over 2 billion edits.
