Introduction

Xamarin is a platform that allows us to create a multi-platform app for Android, Windows, or iOS through a single integrated development environment (IDE). And with Xamarin.forms, the interface design for all three platforms can be accomplished within its XAML-based standard, native user-interface control.
Step 1
Open Visual Studio and go to New Project >> Installed >> Visual C# >> Cross-Platform.
Select the Cross-Platform app, then give your project a name and location.
