Windows Workflow gotcha #2


Windows Workflow gotcha #2

We had more fun with Windows Workflow Foundation (WF) 4 over the last few days - another silent death error.

Again, Maurice helped us out.

If you try to promote a DateTime property containing DateTime.MinValue (or any date before the year 1753), SqlWorkflowInstanceStore will fail silently. SQL Server doesn’t support earlier dates.

Once you know that the trace source name is “System.Activities.DurableInstancing” you can actually see these errors.
