If you are going to use knockout js. give a look to Mvc Controls Toolkit Client Blocks. They are built on top of knockout js, and add to it, Mvc validation, globalization, strong typed byndings, you can bing model properties also to complex javascript widgets. Finally, bindings are defined automatically based on the same name convention used by the default model binder, and the client viewmodel side is automatically serialized and sent to the client...and on post deserialize and put in the right place within the server side ViewModel. You can write knockout powered views as normal razor views forgetting about bindings and client model handling...everything is handled auomatically by the framework...You have just to add the client side javascrit SPECIFIC for your application all "Hard Plumbing" is handled automatically.
