Coming from Rails I’d grown quite fond of flash messages. Unfortunately there isn’t a built in way of doing this in MVC4. Luckily, there’s a five minute solution posted on StackOverflow: http://stackoverflow.com/a/11809178/522859
Once implemented, it works just like in Rails:
this.Flash("We need you to login before you can edit anything.", FlashEnum.Warning);
Definitely worth checking out if you’ve got time, even more so if you’ve come over from Rails!
