In my MVC app the controller gets the data (model) from an external API (so there is no model class being used) and passes that to the view. The data (model) has a container
This is how you call an instance method on the Controller:
@{ ((HomeController)this.ViewContext.Controller).Method1(); }
This is how you call a static method in any class
@{ SomeClass.Method(); }
This will work assuming the method is public and visible to the view.
