Xamarin
Xamarin in no time became the most trusted and widely used cross-platform app development tool. It helps in evading bugs, enhancing the quality, productivity and look of the app. Share code written using Xamarin easily across multiple platforms as it reduces the common platform-specific errors.
A cloud-based app building platform compiles HTML, CSS, and JavaScript code into native code, without requiring updates or maintenance to the native SDKs behind your apps. In 2013, Xamarin Studio was introduced, a tool that allows developers to build mobile applications using the C# language. It also announced its integration with Microsoft’s Visual Studio. It made easier for developers to continue using their favourite mobile app development environment.
