In today's world, you may write your smart client app in UWP, Xamarin, WPF, or even Windows Forms. In each case, your app probably calls back-end services and needs to interact with app servers. Some or all of your business logic runs on the client, the app server, or both–at least that would be the ideal to get a balance between user interactivity, performance, scalability, and security. The widely used open source CSLA .NET framework helps you create a reusable, scalable, and x-plat portable business layer that lets your application run on multiple types of client devices while sharing business logic between the clients and your app server. You'll get an end-to-end walkthrough of how this works and how it can benefit you during this session.
