I am currently using the 3.0.4513.0 build of WiX.
I have been using TFS to distribute the MSI's to our development team. Recently I changed the project properties of my WiX projects such that they output directly to the location within my workspace where the MSI's live so that my process changes from {build->checkout->copy output->check in} to {checkout->build->check in}
However, now if I forget to checkout the output before attempting a build, when the build process attempts to write to the read-only file a series of access-denied errors, HRESULTS, and a crash of the IDE occur (Using VS2008 SP1)
