MVC4 API on Azure WebSites or Azure Cloud Services [Error] : 'System.ComponentModel.DataAnnotations.Schema.DatabaseGeneratedOption'

Question

I am getting this error when I try to deploy my Web API project to both Cloud WebSites and Cloud Hosted Services on Azure:

\"{\"ExceptionType\":\"System.Type         


        

Answer 1

So it seemed that the problem was caused by me rolling back to .NET 4 from 4.5 and Entity not rolling back. It seems that Entity 5 only runs on .NET 4.5 and when the deployment was expecting 4.3.1 it had a 5.0.0 DLL and it messed everything up.
