In this episode, Jon and Allan discuss various topics related to creating and maintaining libraries and NuGet packages. They talk about their experiences with plugin libraries and the importance of supporting open source developers. They also touch on the challenges of avoiding vendor and framework lock-in. Overall, the conversation highlights the value of community-driven development and the need for collaboration and appreciation in the open source world. The conversation explores the process of creating libraries and plugins for cross-platform development. It delves into the challenges of balancing dependencies and code size, as well as the evolution of library development over time. The role of Microsoft Extensions and dependency injection in library development is also discussed. The conversation concludes with a discussion on the improvements in Maui and the use of Microsoft Extensions and DI in the framework. This part of the conversation explores the importance of familiar patterns and dependency injection in Xamarin development. It discusses the trade-off between performance and app size, as well as the challenges of implementing dependency injection in Xamarin.Forms. The conversation also touches on the growth of plugins in the Xamarin ecosystem and the controversy surrounding Reactive Extensions (RX). The creation of Xamarin Essentials and its goal of pleasing the majority of developers is highlighted, along with the focus on testability in Shiny. The chapter concludes with a discussion on the trade-off between performance and interfaces. In this conversation, Jon and Allan discuss various topics related to open source development, including generating interfaces and wrappers, elevating to platform API level, simplifying abstractions, creating custom implementations, using files and folders for caching, managing GitHub repos and libraries, forking and cloning repos, cleaning repos and business continuity, and appreciating open source contributors.
