Xamarin is Microsoft’s single-codebase application development platform that provides mobile app developers with a toolset to write code once, then release to multiple mobile platforms. This effectively cuts the development effort down to nearly half of the traditional native mobile app development lifecycle (I.e. creating one dedicated app for Android, then the same but completely-separate dedicated app for Apple devices). In addition, Xamarin runs atop Microsoft’s powerful and enterprise-grade .NET Framework, giving it the base framework required to ensure uptime and stability across a broad range of apps with an even broad range of users. In the hands of seasoned .NET Stack developers like the Medullus Systems mobile application development team, Xamarin sets the stage for quicker delivery of more powerful cross-platform mobile apps.
