This post serves as an introduction to the ways you can reference HTML elements in your components in Vue.js. You can toggle between views or component templates by using the Vue router or by creating dynamic components. 

The Xamarin Live Player helps you get started with Xamarin.Forms development by learning to build mobile apps that you can test on your Android or iOS device

TDD means letting your tests drive your development (and your design). You can do that with unit tests, functional tests and acceptance tests. Usually, you use all three. 

You can use the Themes of .NET Tool (themesof.net) to identify roadmaps and progress on various .NET releases.
