Is it possible that the update to PD12 has somehow affected Visual Studio's ability to "watch" directories within the \\Mac share? Since upgrading to Parallels Desktop 12, Asp.Net MVC views are not always refreshed in the browser after they have been saved during a debugging session. Saving several times sometimes causes the view to refresh, but usually I need to restart the debugging session. The MVC project is saved via a drive mapped to the parallels \\Mac share.
