Xamarin allows developers to build native iOS, Android, and Windows apps using C# and shared codebases. Developers can use Visual Studio on Windows or Xamarin Studio on Mac to build apps that share a common C# backend while having truly native UIs. Xamarin's tools include Xamarin.Forms for building cross-platform UIs, test frameworks, and services for distributing, getting feedback, and monitoring apps in the wild. Xamarin allows building mobile apps faster by sharing significant code across platforms while still delivering high performance native experiences.

Visual studio + Xamarin == LoveAdam Hill

This document summarizes a presentation about how Visual Studio and Xamarin can make mobile development easier. It notes that mobile development can be challenging due to different platforms and devices. Xamarin allows developing apps using C# that can target iOS, Android and UWP. Since Microsoft acquired Xamarin, it is now free and integrated into Visual Studio. Popular frameworks like MVVM, IoC containers, and testing tools work with Xamarin. The document provides an example of an app developed for a conference in only 6 weeks that deployed to iOS, Android and UWP. It emphasizes that Xamarin streamlines cross-platform mobile development while reusing most code.

Mobile Cross-Platform App Development in C# with XamarinNick Landry

Building native applications across multiple platforms is hard. iOS requires knowledge of Xcode, the iOS SDK and Objective-C or Swift. Android requires Eclipse (or Android Studio), the Android SDK and Java. The Windows 10 Universal Windows Platform requires Visual Studio, C# and the WinRT SDK. Are we really expected to learn all of this? You can take the HTML5 & Cordova route, but not all apps should be built using a hybrid approach. If you want to create a truly competitive app with a premium experience, you’ll need to go native. Fortunately, there is a way you can share a lot of your code across mobile platforms and do so using the C# language you already know and love. Xamarin is a powerful toolset that allows developers to write native Android and iOS apps using C#, thanks to the Mono framework – an Open Source project that brings the C# language and .NET to other platforms. This session explores how you can build cross-platform applications for iOS, Android, and Windows using C#. You’ll learn how to get started with a sample cross-platform solution, which tools you can use, how to design a proper user interface for each platform and how to structure your projects for maximum code reuse. We’ll also look at how you can share UI code with Xamarin.Forms. Native mobile development doesn’t have to be so hard. Come learn how your .NET skills can be transformed for true cross-platform development.

"Intro to-xamarin.forms", Кирилл Стативкин, Microsoft Student PartnerAlina Vilk

This document introduces Xamarin.Forms, which allows developers to write native mobile apps using C# that share code across platforms. Xamarin.Forms apps have native performance and access platform APIs while using shared UI code, layouts, and controls defined in C# and XAML. This allows building iOS, Android, and Windows apps with one shared codebase instead of maintaining separate codebases. The document demonstrates building an app with a tabbed page layout and shared login page in XAML, and discusses Xamarin.Forms' included layouts, controls, and platform API coverage on iOS, Android and Windows.

This SlideShare presentation is from our May webinar, “Not So Common Memory Leaks & How to Fix Them?”, where we explored lesser-known memory leak patterns in Java applications. Unlike typical leaks, subtle issues such as thread local misuse, inner class references, uncached collections, and misbehaving frameworks often go undetected and gradually degrade performance. This deck provides in-depth insights into identifying these hidden leaks using advanced heap analysis and profiling techniques, along with real-world case studies and practical solutions. Ideal for developers and performance engineers aiming to deepen their understanding of Java memory management and improve application stability.

TestMigrationsInPy: A Dataset of Test Migrations from Unittest to Pytest (MSR...Andre Hora

Unittest and pytest are the most popular testing frameworks in Python. Overall, pytest provides some advantages, including simpler assertion, reuse of fixtures, and interoperability. Due to such benefits, multiple projects in the Python ecosystem have migrated from unittest to pytest. To facilitate the migration, pytest can also run unittest tests, thus, the migration can happen gradually over time. However, the migration can be timeconsuming and take a long time to conclude. In this context, projects would benefit from automated solutions to support the migration process. In this paper, we propose TestMigrationsInPy, a dataset of test migrations from unittest to pytest. TestMigrationsInPy contains 923 real-world migrations performed by developers. Future research proposing novel solutions to migrate frameworks in Python can rely on TestMigrationsInPy as a ground truth. Moreover, as TestMigrationsInPy includes information about the migration type (e.g., changes in assertions or fixtures), our dataset enables novel solutions to be verified effectively, for instance, from simpler assertion migrations to more complex fixture migrations. TestMigrationsInPy is publicly available at: https://github.com/altinoalvesjunior/TestMigrationsInPy.

Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik

Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe. We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved? Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.
