Mike Wasson's article "Dependency Injection for Web API Controllers" on www.asp.net says:
Dependenecy Scope and Controller Lifetime
Controllers are created per request…
Am I correct in understanding that ASP.NET Web API creates a new controller instance (and satisfies its dependencies) for each incoming request?
Is this approach not wasteful in that it creates and destroys many instances of the controller when in theory a single instance could be used for all requests?
