Exception handling in Workflow is somewhat different than how we do in normal .NET application. Below is the numbered snapshot of how we can handle exceptions in Workflow.
- We have small tab, which says view exceptions. If you click on view exception, you will be redirected to a workflow design only for exception as shown in numbered snapshot 2.
- This is the workflow which will execute incase we have exceptions. We have put a code activity, which points to a method called as raise Exception. Incase of exception in the workflow this path will be followed.
