I've got a Visual Studio 2008 solution with 4 projects in it. I publish all of them using VS2008's publish feature. VS complains consistently about one of the projects that it cannot remove the _vti_pvt folder and I have to go delete the folder and republish. None of the other web folders have a _vti_pvt folder and I don't use FrontPage.
What causes VS to generate this folder and more importantly, how do I dispense with it?
