In this universal application context, developers are now finding it difficult to get the necessary solutions for common tasks on all three platforms. When considering Xamarin applications, the term, universal, refers to applications that run on all three platforms and adapt to the system resources. With the release of Xamarin, a truly universal application concept was born. However, the same term is now used to describe Windows Runtime applications (Windows Store and Windows Phone 8.1 - WinRT) and Android applications for phones and tablets. Universal application is a term previously used to identify applications targeting devices running on the iOS operating system (the iPhone and iPad). There is also a direct correlation between the robustness, the effort required for maintaining a multi-platform application, and the reusable modules.

The shared code and assets between the development projects improves the elegance and the quality of the work.

Developers are enjoying a new era in which development is not restricted to one single application platform but spans across various media such as cellphones, tablets, personal computers, and even wearable devices.
