title: Visual Studio creating IIS virtual directories when solution opened
body: <p>Visual Studio is asking to create virtual directories in IIS when I open a solution. Could this be because projects within the solution have been configured to use IIS rather than Cassini?</p>
  
  <p>The dialog message is:</p>
  
  <p><em>"The local URI ... specified for Web project ... has not been configured. In order to open this project the virtual directory needs to be configured. Would you like to create the virtual directory now?"</em></p>
