cloud site PnP provisioning office 365 add-in model

I am trying to build a customised async timer job for site provisioning using add in model.

https://channel9.msdn.com/blogs/OfficeDevPnP/Self-service-site-collection-provisioning-to-Office-365-with-Azure-WebJob

I am using the PnP solution

https://github.com/SharePoint/PnP/tree/dev/Samples/Provisioning.Cloud.Async.WebJob

 While building the solution, i got the following errors:

Severity Code Description Project File Line Suppression State
Error Could not copy the file "app.config" because it was not found. Provisioning.Cloud.Async.WebJob
