Hi,
I had builds running in TFS2010 with FinalBuilder, but then I installed the latest version and uploaded the latest WF .xaml files. Now I get the following error:
TF215097: An error occurred while initializing a build for build definition \Tellus.Core\Tellus.Core Development: Cannot set unknown member 'VSoftTechnologies.FinalBuilder.TFS.Workflow.FinalBuilder.CreateTriggerFile'.
Any ideas?

Hi Dennis,
It looks like there’s an inconsistency between your custom XAML template and the FinalBuilder workflow activity. The usual cause is that TFS has cached the FinalBuilder assemblies and is still using the old version. Restart the TFS services (controller and agents) to force it to re-load the assemblies.
If you’ve already done that let me know and we can dig in a bit further.
Cheers,
Ben

No problems - glad you’re up and running.
