Define Xamarin?
Xamarin is basically a cross-platform technology that uses a single codebase with C# where the user can build suitable native user interfaces as well as native applications for platforms such as Windows, macOS, etc. It is a one-stop platform whose tools can be used in any of the operating systems and thus various applications can be developed which can run on these platforms without any kind of significant change in the code.
