Microsoft Releases .NET 8 Release Candidate 1 with New AOT Modes and JSON Handling Capabilities

.NET 8 RC1 brings with it a slew of new features and improvements including faster startup times and improved runtime performance


has announced .NET 8 Release Candidate 1. This release is a precursor to the final version, expected to be unveiled in November, and offers a sneak peek into the advancements and improvements that developers can anticipate.

Key Features and Enhancements

.NET 8 RC1 brings with it a slew of new features and improvements. One of the most notable is the introduction of a new AOT (Ahead-of-Time) mode for both Android and WebAssembly (WASM). This mode promises faster startup times and improved runtime performance, albeit at the cost of a slightly increased app size.

Another significant enhancement is in the realm of JSON handling. The System.Text.Json library has seen several improvements, including the addition of IAsyncEnumerable streaming deserialization extension methods. This allows for more efficient and streamlined handling of JSON data, especially when dealing with large datasets.

Azure Managed Identity support for containers is another noteworthy addition. This feature facilitates easier and more secure authentication when working with Azure services, eliminating some of the hassles developers often face when integrating Azure into their applications.

Community Contributions and Collaborations

The .NET community has always been vibrant and active, and this release is no exception. Several features and improvements in .NET 8 RC1 have been contributed by community members. For instance, the IAsyncEnumerable streaming deserialization extension methods for System.Text.Json were contributed by David Pine, a community member known as @IEvangelist. Such contributions underscore the collaborative nature of the .NET ecosystem and how it thrives on shared knowledge and expertise.

Looking Ahead: .NET Conf 2023

Developers and .NET enthusiasts have more to look forward to. The dates for .NET Conf 2023 have been announced, and the event is set to take place from November 14-16, 2023. This conference will undoubtedly be a significant event, celebrating the official release of .NET 8 and offering insights, workshops, and discussions around the platform's future.
