In this chapter, we saw that using POCO controllers is not really needed, and it requires more work than whatever benefit we can take out of it, so we should have our controllers inherit from Controller.
Then we saw that using asynchronous actions is good for improved scalability as it won't affect performance much, but your app will be more responsive.
You can forget about XML formatting, as JSON works perfectly, and is the standard way to send and process data on the web.
We learned that we should use POCO classes as the model for our actions. The built-in model binders work well, as we'll see in upcoming chapters, but you can add the cookie value provider as it may come in handy.
As far as model validation is concerned, we saw that it is better to stick to the good old data annotations API. If necessary, you should implement IValidatableObject in your model.
