Recently upgraded my wix to 3.0.4721.0 in visual studio 2008 team edition for developers. Now, when I try to edit a file that's checked in (TFS), it isn't automatically checked out.
This happens in any project within a solution with a wix project.
I verified all source control settings as being correct.
I opened a different solution without a wix installer project and verified checkout on edit still works.
I uninstalled wix and verified checkout on edit works for the same solution (now without the wix project) that it didn't work in before.
I reverted to 3829 and everything works as expected again.
It's a known issue with moving from older versions of Votive. See http://blogs.msdn.com/jasongin/archive/2008/07/09/votive-project-platform-configurations.aspx for details and workarounds.
