J'ai lu que vous pouvez utiliser un ViewModel pour votre _Layout en rasoir, mais je ne vois pas d'exemples ...Exemple de mise en œuvre d'un ViewModel pour le rasoir _Layout.cshtml
Au sommet de mon _Layout j'ai ..
@inherits System.Web.Mvc.WebViewPage<CAPPortal.ViewModels.MasterViewModel>
, mais chaque fois que je tente d'accéder à l'une des propriétés que je reçois une erreur ..
System.NullReferenceException: référence d'objet non définie à une instance d'un objet.
Line 23: @Model.Foobar
Exception:
[NullReferenceException: Object reference not set to an instance of an object.]
