>>Its your routing. First, your first route has runsheetdetails in the template, and no controller. When if finds a url matching this template it is going to use the default controller. Second, you are missing a route for your MVC controllers. The only routes you have include api as part of the template. Also, MVC routes usually include an action component as part of the template. Finally, I'm guessing that your RunSheetDetailsController isn't matching any methods for your action. Your index action doesn't take parameters, and the get method is mapped to the action of edit. Being mapped to a different action may prevent it from being used implicitly.

Probably a bit late to suggest this but I switched away from the old convention based approach and use Attribute routing:

More flexible - and much easier to get your head around :-}
