D365FO: workflow development and debugging

There are many guides in the internet how to create a new workflow in D365FO. The process is quite long and complicated.

Here are some of the tips to make it easier for you:

1. If you stuck and not sure how to implement a specific part of a workflow - check Microsoft's workflows from Application Foundation model. Many good examples there.
   
   
2. When you debugging the workflow, remember to attach your Visual Studio to the "Batch.exe" process, not to the default "iisexpress.exe", else no breakpoint will be hit
   
   
3. The "Rejected" workflow action for some reason is handled by "denied" event handler (WorkflowElementDeniedEventHandler). All other actions (Started, Approved, Canceled, etc.) have event handlers with matching names.
