In this chapter, we learned about the need for validation and the different kinds of validation available. We have even discussed how client-side and server-side validation work, along with the pros and cons of each type of validation. Later, we made code changes to validate the input data at the server side. Then we used JavaScript to validate the input data in the client side itself. Finally, we used the jQuery unobtrusive library to do the client-side validation without ever writing the JavaScript code to validate the input data at the client side.

In the next chapter, we will discuss the routing principle and how to customize it. In an earlier chapter, we saw the basics of routing in an ASP.NET 5 application. Now we are going to explore this topic in depth.
