We could not implement all features of .NET 6, however. ARM machines are not supported as development machines or build agents, only as run-time platforms. If you are affected by this limitation, please reach out to us and we will discuss your situation personally.
PostSharp 6.10 is a long-term supported (LTS) release, pinned to .NET 6.0 LTS. As an LTS release and according to our support policies, we will support it until one year after our next LTS release. We will still provide support and bug fixes for PostSharp 6.5, the previous LTS version, until December 2022.
Most of our development efforts now go the next generation of PostSharp, a technology called Project “Caravela”. You should hear more from us about this project very soon.
Happy PostSharping!
