## What is Invention Manual?

Invention is how you build cross-platform, native apps with a single C# codebase.  This is an interactive manual for learning how to develop in Invention.

Benefits of Invention:
- Code-first API with no XML files
- Layout is arrangeable and composable
- Compiles to a native app
- Rapid development in Visual Studio
- Live editing with Roslyn

Write your app code in .NET Standard class libraries using the Invention API. The iOS platform is built on Xamarin technology. Write your app once and deliver to the major app stores.

Microsoft Visual Studio Community Edition with Xamarin and the open-source Invention Library makes mobile app/game development in C# both free and easy.
