Create Timer Task Application In Xamarin.Forms Using Visual Studio

Xamarin Introduction

Xamarin is the best cross platform tool to develop mobile applications. It provides cross platform app development in C#, so we don’t need to write in Java or Objective C. We can just use C# and leverage the same for all the platforms. Xamarin also helps us by providing the designers with the different platforms like Android, iOS, etc.

Working with Xamarin application development, we have two gateways- Xamarin Studio and Visual Studio. Xamarin Studio supports for both Windows or Mac. Visual Studio supports only in Windows, provided you can build and debug on Mac.
