The main task that separates us from the Release Candidate status is API and reference documentation. That’s what we are going to work on during the next couple of weeks. The API could still change during this process because documenting also works as an excellent review process.
If you are already using PostSharp 2.1, it is now a good time to try to upgrade to the next version and see if anything goes well. We don’t recommend you to “commit” the upgrade to your main development branch yet (and the PostSharp 3 does not come with a go-production license yet), but it would really help us to have feedback from the field. To upgrade to PostSharp 3, just use NuGet package manager at solution-level and add the pre-release PostSharp package to all projects.
We’re looking forward for your feedback.
Happy PostSharping!
