Top 10 Frequently Asked Xamarin Interview Questions

Xamarin is a Microsoft Cross-Platform Mobile Development solution that allows us to create native apps for all platforms (IOS, Android, and UWP) using the C# language. For app development, Xamarin uses two methods: Xamarin. Forms and Xamarin Native. Forms, while native UI technology and MVC or MVVM Cross Architecture are used in Xamarin Native. MVVM and XAML are used in Xamarin.

If you want to enrich your career and become a professional in IOS Development, then enroll in “IOS Development Training“. This course will help you to achieve excellence in this domain.

Tell us about xamarin.forms and why we use them?

Xamarin. Form is a cross-platform toolkit that allows you to exchange business logic and UI across all supported platforms using XAML. The form was accomplished using the MVVM pattern and binding into the XAML UI. For each platform, it generates pure native controls. We can share the entire business logic, and the user interface across all supported platforms, such as iOS, Android, and UWP, using Xamarin.Forms. Renderers can also be used to customize any native controls for a particular platform. Because of that near, about eighty to ninety percent of code will be shared between different platforms. Xamarin is the King of Cross Platforms, as far as were concerned.

Q 2: Regarding MVVM

Just as other cross-development frameworks, Xamarin has adopted MVVM (Model-View-ViewModel) paradigm against the MVC.MVVM is a software architectural pattern that facilitates the separation of business logic from the presentation. Thus, designers and programmers can work together simultaneously on the same project. Thus, you should ask a question regarding MVVM in detail.

What is the difference between android studio and xamarin?

The most significant distinction between Android Studio and Xamarin is their build systems. Android Studio uses Gradle for application development, whereas Xamarin uses MS Build. There are very differences between these two IDEs. Xamarin is more user-friendly than Android Studio, which offers a more sophisticated user interface.

Objective-C, Java, C, and C++ Interop – Xamarin provides facilities for directly invoking Objective-C, Java, C, and C++ libraries, giving you the power to use a wide array of third party code. This functionality lets you use existing iOS and Android libraries written in Objective-C, Java, or C/C++.

Is Xamarin good for app development?

Its goal is to unify the development of mobile apps with one code base to speed up the development process while maintaining as many of the native features of each platform as possible. Xamarin can be the right option for teams that need to turn over a mobile app for many platforms in a short amount of time.
