The .NET team has released the first public preview of its upcoming major update, .NET 11. This annual release cycle helps the platform introduce new features and improve its core infrastructure independently of Windows updates. Developers now get regular previews to experiment with upcoming changes and see how they might impact their code. Although the full feature set isn’t ready yet, this preview offers a valuable glimpse into the future of .NET and its evolving capabilities.

Focus on Infrastructure Over New Language Features

Interestingly, the first preview doesn’t highlight new language features. Instead, it emphasizes improvements under the hood—specifically to the compiler and runtime. These foundational changes reveal the team’s direction for future releases and hint at where .NET is headed in terms of performance and cross-platform support. As these core elements evolve, developers can expect a more consistent and efficient experience across all platforms.

While new language features are still in development, the infrastructure updates are crucial. They set the stage for future enhancements and make it easier to build and run applications with better performance and compatibility. The team is actively tracking progress on GitHub, and this ongoing work signals a focused effort to strengthen the platform at its core.

Major Changes for Android and WebAssembly

One of the most significant updates involves moving away from the Mono runtime for Android applications. Instead, .NET will now use CoreCLR across all platforms. The Mono runtime has been part of .NET’s WebAssembly and Android implementations, but the switch to CoreCLR aims to unify the platform. This change will enable developers to access the same features on every device and platform, fostering more consistent behavior and easier maintenance.

The transition is still in early stages, with initial SDKs and interoperability work completed. Performance improvements, especially in startup times, are expected as part of this move. For WebAssembly, the goal is to support running more complex applications beyond simple “Hello World” examples. The project aims to support RyuJIT for WebAssembly by the end of the .NET 11 cycle, with full support expected in .NET 12. This compatibility will make it easier to develop and deploy web applications with .NET, both on the server and client sides.

Developers are encouraged to experiment with these new WebAssembly capabilities in Preview 1. While full support isn’t available yet, exploring the early versions can help guide future development and prepare applications for the upcoming platform improvements.

New Support for Distributed Computing

An exciting feature in this update addresses how applications can run and communicate across multiple machines or services. With more code now needing to operate in distributed environments, .NET is evolving to better support these scenarios. This means building applications that can seamlessly distribute work and interact with external APIs will become easier, opening doors for more complex and scalable software solutions.

This move reflects a broader shift in software development, where applications are less tied to a single machine and more focused on cloud and distributed architectures. The improvements aim to simplify the process of creating applications that are responsive, scalable, and capable of working across different environments.

Overall, the first preview of .NET 11 offers a promising look at a platform that’s becoming more powerful and flexible. Although some features are still in progress, the underlying infrastructure changes set the stage for a more unified, performant, and future-ready development experience. Developers can keep an eye on ongoing updates and start experimenting with these new capabilities today to shape the next generation of applications.
