VS appears to color this blue as a keyword, even with VAX turned off, at least in VS 2010. I haven't tried any newer editions. If it's marked as a keyword in VS 2013 Community Edition, that's a VS bug.
A little unexpected. A function called "event" is shown in blue in VS2010 even when VA has never been installed on the machine, so this is something that is coming from the IDE, not from us.
I am seeing the problem with Move Implementation to Source File not being offered, and I have put in a bug report for this:
is the issue on connect, but they're acting all stupid and saying that they can't reproduce, which is exceedingly lame because this has been a problem ever since C++/CLI was introduced.
