The model item passed into the ViewDataDictionary is of type X[] but this ViewDataDictionary instance requires a model item of type X [duplicate]

Answer 1

The problem is that the Layout the View is using expects a model of Ticket and you are passing it a Ticket[] (notice that this is done implicitly when you use return View(model)).

Normally, since the Layout is used through multiple Views, the Layout does not declare a @model. Removing the @model from the Layout will solve your problem.
