I have an ASP.NET 5 solution with a website and several project libraries. I'm using MVC 6 and Entity Framework 7. Locally the app is working fine and until today it was working also on Azure deployed as an Azure Website.
But today after the latest deployment on Azure I got an error 500 like this on the startup (still working fine locally):
I tried to get more details by :
- using middleware diagnostics
- adding the customError / httpError settings in the web.config file
- downloading the DetailedError page generated
It seems that the error/exception is happening during the Startup/Configure step but I'm still getting the generic error page without details. Even the version generated on the server (DetailedErrors folder) I got this:
I enabled the Failed Request Tracing but still no useful information:
Even if I strip down the code in the Startup/Configure and add a try/catch as suggested I got the same error without détails. It seems to be a configuration/compilation issue but hard to debug without any information.
