I'm playing a constant game of modifying files until my changes are registered correctly in the file system.</p>\n\n<p>For example, one publish profile that I edited and \"saved\" using the prompt has its pubxml file marked as delete. I suspect the profiles are cached and Visual Studio 2013 is not reflecting what's in the file system in real time.</p>\n\n<p>The save prompt only shows up when I go to another profile or hit the publish button. It would be nice to have a save button that would force the pubxml files to show the latest.</p>\n\n<p>Does anyone have a clear workaround this? I had a similar experience with web.config transformation in the same project and ended up editing the project file.</p>\n\n<p>I'm certain this is not bound to the specific project I am currently dealing with as I see the same behavior in other projects. I never had this issue in Visual Studio 2010.</p>\n\n<p>You'll not see this issue if you have just created new profiles. I am only seeing this behavior when I modify the existing profiles.</p>\n", "Lable": "No"} | |
