Hi,
I happen to have visited this site when version 1.45 was released. Within VS2010 however, there was no update through the Extension Manager (uninstall and disable buttons are both disabled; updates tab is empty).
If I missed the announcement on the site, there was no way I was notified about the new version.
Is this a known issue? If so, maybe you should notify customers by mail? A 'Check for updates' option in the nCrunch menu would be nice too, if this is the case.
Thanks,
Niels
