The models referenced in the KendoUI for ASP.NET MVC examples are not part of the Kendo.Mvc.dll
assembly. Instead, you must download them from your Telerik account. Go to telerik.com and sign in. From there, navigate to your Products & Subscriptions and locate "KendoUI for ASP.NET MVC" and select "Browse all product files". Download the "Manual Installation" file and unzip it.

You'll find the examples (and the referenced models) in the wrappers\aspnetmvc\Examples
folder.

If you want to reference the models in your project, just grab a copy of the compiled assembly Kendo.Mvc.Examples.dll
from the bin folder of the example project. Keep in mind this will include everything from the examples (controllers, models, view-models, etc.).
I hope that helps.
