Exception when ASP.NET MVC 5 app is deployed in RELEASE mode

ASP.NET5

Dear Members

I am developing a ASP.NET MVC 5 application as a Outlook web add-in. It uses Azure AD for authentication.

My issue is - If I publish it in debug mode, it works fine.

If I publish it in release mode and try to authenticate the new user, it throws the following exceptions. The exceptions seems to originate from System.Web.Mvc.

Here is the stack trace -

StackTrace :    at System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(RequestContext requestContext, Type controllerType)

What I have tried:

Removed all transformations from debug and release mode so that there wont be any chances of conflicts/errors while changing the release mode.
