I have been investigating leveraging WF in my company's product suite for health/life business scenarios. I like the technology and architecture of the tools and was wondering what success stories anyone has had with WF they could share? Has anyone gone into production with beta or release candidate? What types of applications are you applying WF to? What are the operating performance criteria that your solutions/products need to meet?

Our current home grown product for health claims adjudication process is capable of launching 1,000,000 long running human centric workflows in an hour? Has anyone attempted these type loads or have any scalability testing they can share?

Thanks.

You can read the published case studies here. We only have a couple published so far as it takes time from when a customer goes live to where we have a completed case study:

We will be publishing a whitepaper on the performance of Windows Workflow Foundation at the same time as the release. That's not too far away now.
