This sample highlights two major improvements in .NET MAUI 10 that significantly enhance XAML productivity and performance: Implicit/Global XML Namespaces and the .NET MAUI XAML Source Generator.
.NET MAUI 10 reduces the noise in XAML files by letting developers define XML namespaces globally instead of repeating them on every page. This removes the common overload of xmlns: declarations and allows XAML to be written with minimal clutter. The implicit namespace feature further streamlines pages by assuming the MAUI global namespace automatically. As a result, XAML becomes easier to read, maintain, and write without losing compatibility with older patterns.
The new XAML Source Generator compiles XAML into C# at build time instead of interpreting it at runtime. This shift makes UI loading dramatically faster, especially in debug builds and provides more consistent behavior across configurations. Developers also benefit from earlier error detection and the ability to inspect generated output, creating a more transparent and reliable development workflow.
When combined, these features bring major day‑to‑day advantages:
- Cleaner, more focused XAML with far less boilerplate
- Significantly faster startup and build performance
- Clearer debugging and earlier validation of issues
- A smoother, more modern development experience overall
If you are facing a path too long exception when building this example project, close Visual Studio and rename the repository to a shorter name before building the project.
