I've installed Framework 4.5 Beta and MVC 4 Beta on a development server.
Try as I might I have not been able to get the server to return details of the error.
There is nothing in the event log of the server. The failed request tracing only mentions the error occured during processing of the request, but no other details. All variations of suggested changes to the config (http://stackoverflow.com/questions/2640526)
failed to provide details of the actual error.
I eventually debugged the issue by commenting out sections of the code and repeatedly deploying.
The services deployed on the remote server still do not return details when an exception is thrown.
If anyone has deployed .Net 4.5 and MVC 4 Beta and are able to retrieve error details then I'll be very keen to hear from them.
Otherwise I believe this is a significant issue that needs to be looked into.
