  I’ve been using Workflow Foundation now for over a year and it has become an integral part of our architecture and has by and large been very successful. However it is not without it’s issues, the single most being that official documentation is light at best and relevant blog posts are quite rare.   I recently ran into a fairly serious problem after deploying a new release of our Software. The Problem I received this lovely email from our exception tracker: System.Runtime.DurableInstancing.InstancePersistenceCommandException: The execution of the InstancePersistenceCommand named {urn:schemas-microsoft-com:System.Activities.Persistence/command}LoadWorkflow was interrupted by an error. ---> System.Runtime.Serialization.SerializationException: Deserialized object with reference id '73' not found in stream.

Whilst it was fairly simple to implement there has been some major changes between 2005 and 2008 and the majority of online and documentation is based on the 2005 implementation. The most important change is that the Report Server and Report Manager are no longer hosted in IIS which will be a welcomed change to Sys Admins but makes the security model and hosting model vastly different. So far I’ve yet to figure out how to allow Anonymous Access, if anyone knows how to do this leave a comment and it will be most appreciated. Getting Started To get started you’ll want to add a service reference to http://localhost/ReportServer_SQL2008/ReportExecution2005.asmx where ReportServer_SQL2008 is the name you configure in the Reporting Services Configuration Manager. The Web Application files are located in C:\Program Files\Microsoft SQL Server\MSRS10.SQL20...
