File name is not displayed on error page middleware on Mac

[suhasj]

Applying the pending PR on Mac, I was able to get the error page in case of an exception. The file information is not displayed as expected though. Attached screen shot

This is because mono does not give debug information like file name or line numbers in the exception messages (i tried passing --debug switch to mono.exe as well). With a recent fix that I pushed for error page middleware, function names are printed like below. If mono gives file name and line numbers with exception messages, the middleware should automatically handle it. I guess this bug can be closed if there are no concerns.

An unhandled exception occurred while processing the request.

Sure we can check again once we have coreclr support on mac
