shared model across controllers

Question

right now in each of my controller classes i am instantiating a new Repository class to access my DB. Is there a way i can simply create this once (a single repository instance shared across all controllers) and pass into all controllers ?

Answer 1

You could make it a singleton.

Answer 2

Dependancy Injection (or create a base class for all your controllers)

Answer 3

ControllerBuilder.Current.SetControllerFactory(new MyOwnControllerFactory());

In your factory you can set up your repository and pass to ALL controllers.

But of course you better use IoC containers. They have option to create repository once per request / once per app lifetime.
