Ivy is a complete rewrite of the compiler (and runtime) in order to:

• 🚀reach better build times (with a more incremental compilation)
• 🔥reach better build sizes (with a generated code more compatible with tree-shaking)
• 🔓unlock new potential features (metaprogramming or higher order components, lazy loading of component instead of modules, a new change detection system not based on zone.js…) 

As a matter of implementation details, C# tuples are implemented on top of ValueTuple types. 

Git from the inside out 

A self-contained app is a great way to share your application as all components, runtime, and framework are included with the application. All you have to provide is the application .exe file without worrying about the presence of framework or runtime installation status on other machines. 

Playing with the New Windows Terminal 

Web application development has evolved with the rise of new technologies and frameworks. Two of the most popular technologies for building interactive web applications are Blazor and React. In this article, we will compare Blazor and React and highlight their differences with examples.
