.NET MAUI (Multi-platform App UI) is a Microsoft technology for developing native applications across various platforms using a shared C# codebase, succeeding Xamarin.Forms with improved performance and ease of development. It aligns with a hypothetical initiative known as '.NET Aspire', which focuses on innovation, developer empowerment, cost efficiency, community engagement, and integration within the broader .NET ecosystem. By enabling code reuse and promoting collaboration, .NET MAUI supports the goals of modernizing software development practices and enhancing developer capabilities.
