Strange thing today. I have a MVC 5 webapp, that has Webapi capabilities used. Problem is that I get old data when retrieving it from a Webapi controller, but fresh data when retrieving directly from the database.
The issue was in the user of automapper. I had automapper map a datetime taking the timezone in account. I had to search in the database to get the right timezone. There the old value was presented. Probably due to Dependency Injection, there was a different databasecontext loaded, that did not see changes made.
Solution: quit using automapper and map the properties manual in my own Mapper class.
