Orleans is an open-source framework for distributed applications that is included with .NET. Although Orleans can run on-premises, it is mostly used in Azure for massively scalable real-time applications, such as collaborative applications, IoT, and gaming back ends.

Product: Orleans

Near Term (2025–2026)

Orleans is updated on a regular basis. The current major release is version 9 and was introduced in Nov. 2024, following version 8 in Jan. 2024.

Version 7 introduced a new wire protocol, breaking compatibility with version 3. (Versions numbered 4 through 6 were skipped, presumably to align with .NET version numbers.) A migration guide is available, although no end-of-life date for version 3 has been announced.

Long Term (Beyond 2025)

Although it is an open-source project, the majority of the contributions come from one individual within Microsoft, making the future roadmap hard to predict.

Directions Recommends

Exercise caution. Although it is open source, Orelans appears to be a one-man show with the majority of contributions coming from one individual within Microsoft. As such, its future is hard to predict.
