title: ASP.NET website References in Property Pages missing Remove button
body: <p>I just cloned and opened a solution that a colleague has been working on, and there are some references that seem to be misaligned. I wanted to remove and re-add references but when I go into the References list in Property Pages there aren't any buttons to manage the list. </p>
