title: Keeping the controller and view separate by using strongly-typed objects
body: <p>I have a question regarding keeping the controller and view separate. It seems to me that the controller should only pass a model to the view, and the view decides how to display the model. This way, the controller and model stay separate and can be independently developed. However, a lot of tutorials I see online and even in the book Pro ASP.NET MVC Framework, I see a lot of examples using either ViewData["string"] or TempData["string"].</p>
  
  <p>Doesn't this introduce two problems? The first one is that the view is now somewhat coupled to the controller in that it has to know the name of the strings that the controller is setting in ViewData/TempData. The second is that these are loosely-typed, meaning there's no Intellisense. If I was developing the controller, I can't just tell another developer working on the view to just use Intellisense for the model, I'd have to give him the name of the strings, and if I ever change the string names, I'd also have to change it in the view.</p>
  
  <p>I guess ultimately what I'm asking is, is this right? Or am I not understanding something?</p>
