mmm... using System.Drawing, c'era già. La cosa strana è che se per scrupolo lo aggiungo davanti ad imaging quando compilo mi esce un messaggio di errore:
Error while tryning to run project. Unable to start debugging on the web server. Server side-error occurred on sendig debug HTTP.
Poi va bè, la seconda parte penso sia irrilevante, dice di controllare il web config...
