.NET MAUI
.NET Multi-platform App UI (.NET MAUI) is a cross-platform framework for building native mobile and desktop applications with C# and XAML from a single shared codebase. It allows developers to create apps that run on Android, iOS, macOS, and Windows using .NET. It is the evolution of Xamarin.Forms, integrated directly into the .NET platform.
Developers should learn .NET MAUI when they need to build cross-platform applications for mobile and desktop devices while leveraging existing .NET skills and C# code. It is ideal for scenarios where code sharing across platforms is a priority, such as enterprise apps, business tools, or applications requiring native performance and access to platform-specific APIs. Use it when targeting multiple operating systems with a single development effort to reduce maintenance overhead.
