PostSharp Professional is now called PostSharp Framework.

PostSharp Framework includes everything you need to automate the implementation or validation of your own patterns, including the Architecture Framework which used to be a part of PostSharp Ultimate. However, PostSharp Diagnostics is removed. PostSharp Professional customers will be offered a free subscription to PostSharp Diagnostics for the whole duration of their PostSharp Professional subscription that has already been paid for. Please contact our sales team if you’re interested. Support for the license server is also removed. Please contact us if you’re impacted.
