title: Mvc5 pass model to Layout Page
body: <p>I have an MVC 5 site with adminlte template. It's work fine. Now I need pass to some data to _layout page. I need pass to _layout page same info as number of alert, number of email, alert list ecc. I read same document about BaseController where do this operation, i.e. read this data and put in a model, or create an abstract model and put this info into. But is not possibile create this model one time (i.e. on user login controller) and share it in all request without re-create it every controller call? Pratically, as a global singleton variabile.
  Thanks.</p>
