Thorup paid the price for a poor run of results, with the Canaries slipping out of play-off contention after three straight defeats and just one win in their last 10 games.
Norwich are bottom of the form table, having picked up just six points from their last 10 games.
Assistant head coach Glen Riddersholm has left alongside Thorup, with Wilshere now placed in interim charge for the final two games of the season, the first of which is at the Riverside on Saturday.
He’ll be assisted by Tony Roberts and Nick Stanley.

Norwich say they will “progress with their plans of appointing a new permanent head coach in due course”.
Sporting director Ben Knapper said: “Whilst we made this appointment with a long-term focus and in line with our wider club strategy and direction, unfortunately recent results and performances have deemed it necessary for us make a change.
“I’d like to place on record our sincere thanks to Johannes and Glen. They are both fantastic people who worked tirelessly to help improve and move our football club forward.
“We all wish the two of them the best in the next stage of their respective careers.”
