Visual Studio 2013 Restart extension, download it here
This extension tries to simplify the process of restarting visual studio, it also allows you to restart with elevated permissions (usefull for example when starting to debug attached to IIS).
By pressing Restart Elevated command inside the File menu, visual studio will be restarted with admin rights and the current solution/project will be reopened (even command line switch will be restored).
Note
Restarting while running Visual Studio as Administrator would cause VS to restart elevated. Feel free to comment or report any issue.
VS2015 support was made by a community member, based on this extension. Try it out here
