Workflow Hangs (task locked) after dll update

Question

Hello all,

I am developing custom workflows in VS. When I update the workflow code, the already running workflows stop working (normaly I have to restart all pending workflows).

Two questions:

Is this normal?

Is there any way to overcome this limitation?

Thank you.

Best Regards,

André Cunha

Hi,

 

The cause of the issue is: the public interface of the workflow, which has been serialized in the database, has changed and now the new assembly does not know how to de-serialize the workflow data from the database. At this point the workflow will fail as it is unable to serialize the current state and looks like it hanged in "In Progress" state.

I think this blog can help you: http://blogs.msdn.com/malag/archive/2008/07/16/how-to-upgrade-workflow-assembly-in-moss-2007.aspx

 

Hope it can help you.
